Subject: [PATCH] explicitly use DEV_BSIZE align for all bmempools

this is required for Xen xbd(4) in order to not have to use bounce buffers

the alignment is implicitly provided when POOL_REDZONE is not active,
this change makes it also aligned when POOL_REDZONE _is_ active - that is
when (!KMSAN && (DIAGNOSTIC || KASAN))
