btrfs: do not BUG_ON() on tree mod log failure at balance_level()
[ Upstream commit 39020d8abc7ec62c4de9b260e3d10d4a1c2478ce ]
At balance_level(), instead of doing a BUG_ON() in case we fail to record
tree mod log operations, do a transaction abort and return the error to
the callers. There's really no need for the BUG_ON() as we can release
all resources in this context, and we have to abort because other future
tree searches that use the tree mod log (btrfs_search_old_slot()) may get
inconsistent results if other operations modify the tree after that
failure and before the tree mod log based search.
