block: unalign call_single_data in struct request
commit 4ccafe032005e9b96acbef2e389a4de5b1254add upstream.
A previous change blindly added massive alignment to the
call_single_data structure in struct request. This ballooned it in size
from 296 to 320 bytes on my setup, for no valid reason at all.
Use the unaligned struct __call_single_data variant instead.
Fixes: 966a967116e69 ("smp: Avoid using two cache lines for struct call_single_data")
