When getting a fault in the kernel, we checked for biglock and failed
immediately when biglock wasn't held. But there is nothing inherently
wrong with doing copyin/copyout faults without holding biglock, so
just remove the check because it prevent us from doing copyin in
syscall before we grab the biglock.
