f2fs: fix handling orphan inodes
This patch fixes mishandling of the sbi->n_orphans variable. If users request lots of f2fs_unlink(), check_orphan_space() could be contended. In such the case, sbi->n_orphans can be read incorrectly so that f2fs_unlink() would fall into the wrong state which results in the failure of add_orphan_inode(). So, let's increment sbi->n_orphans virtually prior to the actual orphan inode stuffs. After that, let's release sbi->n_orphans by calling release_orphan_inode or remove_orphan_inode.
