btrfs: fix missing semaphore unlock in btrfs_sync_file

Robbie Ko authored 5 years ago

Ordered ops are started twice in sync file, once outside of inode mutex
and once inside, taking the dio semaphore. There was one error path
missing the semaphore unlock.

Fixes: aab15e8e ("Btrfs: fix rare chances for data loss when doing a fast fsync")
