*
* In other words, let's name the min. I/O unit where the corruption
* starts B, and the previous min. I/O unit A. The below code tries to
* deal with a situation when half of B contains valid nodes or the end
* of a valid node, and the second half of B contains corrupted data or
* garbage. This means that UBIFS had been writing to B just before the
* power cut happened. I do not know how realistic is this scenario
* that half of the min. I/O unit had been written successfully and the
* other half not, but this is possible in our 'failure mode emulation'
* infrastructure at least.
*
* So what is the problem, why we need to drop those nodes? Whey can't
* we just clean-up the second half of B by putting a padding node
* there? We can, and this works fine with one exception which was
* reproduced with power cut emulation testing and happens extremely
* rarely. The description follows, but it is worth noting that that is
* only about the GC head, so we could do this trick only if the bud
* belongs to the GC head, but it does not seem to be worth an
* additional "if" statement.
*
* So, imagine the file-system is full, we run GC which is moving valid
* nodes from LEB X to LEB Y (obviously, LEB Y is the current GC head
* LEB). The @c->gc_lnum is -1, which means that GC will retain LEB X
* and will try to continue. Imagine that LEB X is currently the
* dirtiest LEB, and the amount of used space in LEB Y is exactly the
* same as amount of free space in LEB X.
*
* And a power cut happens when nodes are moved from LEB X to LEB Y. We
* are here trying to recover LEB Y which is the GC head LEB. We find
* the min. I/O unit B as described above. Then we clean-up LEB Y by
* padding min. I/O unit. And later 'ubifs_rcvry_gc_commit()' function
* fails, because it cannot find a dirty LEB which could be GC'd into
* LEB Y! Even LEB X does not match because the amount of valid nodes
* there does not fit the free space in LEB Y any more! And this is
* because of the padding node which we added to LEB Y. The
* user-visible effect of this which I once observed and analysed is
* that we cannot mount the file-system with -ENOSPC error.
*
* So obviously, to make sure that situation does not happen we should
* free min. I/O unit B in LEB Y completely and the last used min. I/O
* unit in LEB Y should be A. This is basically what the below code
