[ Upstream commit 7c4042a4d0b7532cfbc90478fd3084b2dab5849e ]

When dif and first burst is used in a write command wqe, the driver was not
properly setting fields in the io command request. This resulted in no dif
bytes being sent and invalid xfer_rdy's, resulting in the io being aborted
by the hardware.

Correct the wqe initializaton when both dif and first burst are used.
