[PATCH 3/4] fnic: missing initialisation for wq_copy_base

[Hannes Reinecke <hare@kernel.org>]

With the conversion to multiqueue the 'wq_copy_base' value were left
uninitialized for MSI and INTx interrupts, causing the driver to issue
a message 'FCPIO_SUCCESS icmnd completion on the wrong queue' and finally
running out of command tags as the completions would be accounted on
the wrong queue.

Fixes: 8a8449ca5e33 ("scsi: fnic: Modify ISRs to support multiqueue (MQ)")
