Btrfs: remove root_log_ctx from ctx list before btrfs_sync_log returns
[ Upstream commit cbd60aa7cd17d81a434234268c55192862147439 ]
We use a btrfs_log_ctx structure to pass information into the
tree log commit, and get error values out. It gets added to a per
log-transaction list which we walk when things go bad.
Commit d1433debe added an optimization to skip waiting for the log
commit, but didn't take root_log_ctx out of the list. This
patch makes sure we remove things before exiting.
