scsi: qla2xxx: Remove duplicate of vha->iocb_work initialization

Commit 9b3e0f4d4147 ("scsi: qla2xxx: Move work element processing out of
DPC thread") introduced the initialization of vha->iocb_work in
qla2x00_create_host() function.

This initialization is also called from qla2x00_probe_one() function, just
after qla2x00_create_host().

Hence remove this duplicate call since it has already been called before.
