scripts/qat_setup: Be more verbose about SR-IOV setup

Browse Source 
If the sriov_numvfs sysfs attr is not available for given controller
report that. Also, verify if number of VFs matches initial value
of 16 devices. If not, report that as well. This number was also
being overwritten with the set value from previous device - this
could false-positive the confirm check so keep the set value in
a seperate variable.
