  Unmasking the interrupt during the pdsc_adminq_isr
is a bit early and could cause unnecessary interrupts.
Instead always unmask after processing the adminq
and notifyq in pdsc_work_thread()->pdsc_process_adminq().
Also, since we are always unmasking, there's no need
for the local credits variable in pdsc_process_adminq().
