hfs: ensure sb->s_fs_info is always cleaned up
commit 05ce49a902be15dc93854cbfc20161205a9ee446 upstream.
When hfs was converted to the new mount api a bug was introduced by
changing the allocation pattern of sb->s_fs_info. If setup_bdev_super()
fails after a new superblock has been allocated by sget_fc(), but before
hfs_fill_super() takes ownership of the filesystem-specific s_fs_info
data it was leaked.
Fix this by freeing sb->s_fs_info in hfs_kill_super().
