Set the FID field in lookaside crypto requests to the rx queue ID.

Browse Source 
The PCI block in the adapter requires this field to be set to a valid
queue ID.  It is not clear why it did not fail on all machines, but
the effect was that crypto operations reading input data via DMA
failed with an internal PCI read error on machines with 128G or more
of RAM.
