got fixed two weeks after the ia64 version was copied from the alpha
version (see rev 1.32 of sys/alpha/alpha/mem.c). As such, we were
missing the same continue as on alpha.
While here, add a default case for the device minor switch and do
some general style(9) cleanups.
WARNING: this file still has bugs. When reading from region 6 or
region 7, we don't validate the physical address. One can trivially
cause a machine check by trying to read from address 0xFFFFFFFFFFFFFFF0
or something that uses the unimplemented physical address bits.
