fs/tmpfs: unlock filesystem on statfs traversal failure
tmpfs_statfs() holds the tmpfs lock while walking the filesystem to
accumulate usage statistics. If tmpfs_foreach() fails, the error path
returned immediately without releasing the lock.
Unlock the filesystem before returning the failure so later tmpfs
operations are not blocked by the leaked lock.
