Subject: block: move timeout field in struct request to pack better

block: move timeout field in struct request to pack better

After commit 64c7f1d1572c, we went from 1 to 2 holes in my
test setup. If we move the timeout field a bit, we remove
both of those holes and shrink struct request by 8 bytes.
