ZFS_READONLY represents the "DOS R/O" attribute. When that flag is set, we should behave as if write access were not granted by anything in the ACL. In particular: We _must_ allow writes after opening the file r/w, then setting the DOS R/O attribute, and writing some more. (Similar to how you can write after fchmod(fd, 0444).) Restore these semantics which were lost on FreeBSD when refactoring zfs_write. To my knowledge Linux does not actually expose this flag, but we'll need it to eventually so I've added the supporting checks.
