Do not check proper request alignment here in geom_dev in production.
It will be checked any way later by g_io_check() in g_io_schedule_down().
It is only needed here to not trigger panic from additional check, when
INVARIANTS enabled. So cover it with #ifdef INVARIANTS. It saves two
64bit divisions per request.
