Artem Bityutskiy 3edaae7c5b UBIFS: improve find function interface
Make 'ubifs_find_free_space()' return offset where free space starts,
rather than the amount of free space. This is just more appropriat
for its caller.

IS_ERR() macro already has unlikely(), so do not use constructions
like 'if (unlikely(IS_ERR())'.

Adrian Hunter 6e14968c86 UBIFS: remove incorrect assert
The assert was not valid because one of the variables
'taken_empty_lebs' has transient values out of sync
with the other variables.

Artem Bityutskiy ad507653a3 UBIFS: fix assertion
The assertion was incorrect, because it did not take into
account free space.

This patch also amends the comments correspondingly, and
cleans them up a little.

Artem Bityutskiy b364b41aeb UBIFS: reserve more space for index
At the moment UBIFS reserves twice old index size space for the
index. But this is not enough in some cases, because if the indexing
node are very fragmented and there are many small gaps, while the
dirty index has big znodes - in-the-gaps method would fail.

Thus, reserve trise as more, in which case we are guaranteed that
we can commit in any case.
