s390x/css: {c,h,t,r,x}sch: require enable AND device number valid
According to the PoP, subchannels are only considered operational if
they are enabled _and_ the device number is valid. With the current
checks being enabled _or_ having a valid device number was
sufficient. This caused qemu to allow IO on subchannels that were not
enabled.
Fix the checks to require both bits to be set.
