nvme-core: choose PIF from QPIF if QPIFS supports and PIF is QTYPE

Browse source

As per TP4141a:
"If the Qualified Protection Information Format Support(QPIFS) bit is
set to 1 and the Protection Information Format(PIF) field is set to 11b
(i.e., Qualified Type), then the pif is as defined in the Qualified
Protection Information Format (QPIF) field."
So, choose PIF from QPIF if QPIFS supports and PIF is QTYPE.
