pf tests: Basic ioctl validation for DIOCRGETTABLES, DIOCRGETTSTATS, DIOCRCLRTSTATS and DIOCRSETTFLAGS
Validate the DIOCRGETTABLES, DIOCRGETTSTATS, DIOCRCLRTSTATS and
DIOCRSETTFLAGS ioctls with invalid values. These may succeed (because
the kernel uses the minimally required size, not the specified size),
but should not trigger kernel panics.
