description:
make sure we pass a valid consdev pointer to the console keyboard so kbd
knows it's console and passes the right flags to wskbd, now the wskbd will
not drop off the mux when leaving event mode.
Symptoms: now the keyboard should no longer be dead when leaving X and there
          should be no more panics caused by it
I tested this on an SS5 and an SS20, may need some more attention and zs.c
sure could use some cleanup - there are a few differences to sparc64 that
really don't make much sense to me, like not passing console flags to zstty
which sparc64 does but sparc avoids, which caused this problem in the first
place.
