Log Message:
zfs: reject all mount op flags for now

- our logic in zfs_vfsops.c is inconsistent. sometimes it checks
  uap->flags, sometimes vfsp->vfs_flag. (aka mnt_flag)

- our userland tools (zfs, mount_zfs) currently don't seem to have
  a way to pass these flags anyway. (zmount in libzfs always passes
  0 to both of mount(2) 'flags' argument and 'uap->flags'. although
  it stores something in uap->mflag and uap->optptr, nothing uses
  them. it doesn't even set MS_OPTIONSTR. we don't implement
  MS_OPTIONSTR anyway.)

this commit simply rejects them for safety. as these operations have
never been implemented in NetBSD, it shouldn't have any impact to users.

maybe someday we should fix these, but i guess it involves some
ABI changes, which i'm not in a mood to do right now.
