[SCSI] remove RQ_SCSI_* flags

The RQ_SCSI_* flags are a vestiage of a long past history.  The EH code
still sets them but we never make use of that information.  The other
users is pluto.c which never had a chance to work but needs to be kept
compiling to keep Davem happy, so copy over the definition there.

We could probably get rid of RQ_ACTIVE/RQ_INACTIVE aswell with some
work, there's only two more or less bogus looking uses in ubd and scsi.
