scsi: megaraid: Pass in NULL scb for host reset
When calling a host reset we shouldn't rely on the command triggering the
reset, so allow megaraid_abort_and_reset() to be called with a NULL scb.
And drop the pointless 'bus_reset' and 'target_reset' handlers, which just
call the same function as host_reset.
