--------------------------------

[ Upstream commit 0a5ec366de7e94192669ba08de6ed336607fd282 ]

The SQ is shared for between kernel and used by storing the kernel page
pointer and passing that to a kmap_atomic().

This then requires that the alignment is PAGE_SIZE aligned.

Fix by adding an iWarp specific alignment check.
