Mark Harmstone 68a135013b btrfs: fix bytes_may_use leak in move_existing_remap() 
If the call to btrfs_reserve_extent() in move_existing_remap() returns a
smaller extent than we asked for, currently we're not undoing the
bytes_may_use change that we made. Fix this by calling
btrfs_space_info_update_bytes_may_use() again for the difference.

Fixes: bbea42dfb9 ("btrfs: move existing remaps before relocating block group")
