f2fs: use generic checking and prep function for FS_IOC_SETFLAGS 

Make the f2fs implementation of FS_IOC_SETFLAGS use the new VFS helper
function vfs_ioc_setflags_prepare().

This is based on a patch from Darrick Wong, but reworked to apply after
commit 360985573b ("f2fs: separate f2fs i_flags from fs_flags and ext4
i_flags").
