f2fs: fix to initialize i_current_depth according to inode type
i_current_depth is used only for directory inode, but its space is shared with i_gc_failures field used for regular inode, in order to avoid affecting i_gc_failures' value, this patch fixes to initialize the union's fields according to inode type.
