Zheng Yan e856981384 Btrfs: allocator fixes for space balancing update 
* Reserved extent accounting:  reserved extents have been
allocated in the rbtrees that track free space but have not
been allocated on disk.  They were never properly accounted for
in the past, making it hard to know how much space was really free.

* btrfs_find_block_group used to return NULL for block groups that
had been removed by the space balancing code.  This made it hard
to account for space during the final stages of a balance run.
