Restore support for in-kernel ZFS ioctls
In Illumos it is possible to call ioctl functions from within the
kernel by passing the FKIOCTL flag. Neither FreeBSD nor Linux support
that, but it doesn't hurt to keep it around, as all the code is there.
Before this commit it was a dead code and zc_iflags was always zero.
Restore this functionality by allowing to pass a flag to the
zfsdev_ioctl_common() function.
