IB/cm: remove unnecessary ib_query_device in PSIF RNR WA

IB/cm: remove unnecessary ib_query_device in PSIF RNR WA

The query device is performed in CM REQ/REP to retrieve the
vendorID of the sif device. This operation is illegal because
it is calling a sleeping function (ib_query_device) from
a non-sleepable context. Thus, this patch removes this illegal
call and reuses the cached vendorID/DeviceID in the pci_dev
data structure.
