A cleanup of opportunity. Since we already are modifying the contents of zfs_mnt_t, we've broken any API guarantee, so we might as well go the rest of the way and get rid of it, and just pass the osname and/or the vfs_t directly. It seems like zfs_mnt_t was never really needed anyway; it was added in1c2555ef92(March 2017) to minimise the difference to illumos, but zfs_vfsops was made platform-specific anyway in7b4e27232d. We also remove setting SB_RDONLY on the caller's flags when failing a read-write remount on a read-only snapshot or pool. Since0f608aa6cathe caller's flags have been a pointer back to fc->sb_flags, which are discarded without further ceremony when the operation fails, so the change is unnecessary and we can simplify the call further.
