SubjectPATCH - use submit_bh in brw_kiovec

Linus,
the new submit_bh function provides functionality that is better
suited for brw_kiovec to use than generic_make_request.

This patch replaced generic_make_request with submit_bh in
brw_kiovec and removed some field initialisation which is no longer
required.

patch against 2.4.0-test12-pre8
