s390/ap: Use all-bits-one apmask/aqmask for vfio in_use() checks

Browse source

For the in_use() check of an updated apmask the host's aqmask
was provided to the vfio function. Similar on an update of the
aqmask the host's apmask was provided to the vfio in_use()
function. This led to false results on the check for apmask or
aqmask updates. For example with only one APQN when exactly
this card is tried to be re-assigned back to the host, the
in_use() check did not complain.

The correct behavior is achieved with providing a full mask
for aqmask when an adapter is to be checked and similar a full
mask for aqmask when a domain is to be checked for usage.
