[PATCH] ipr: Allow Query Resource State adapter command to

The ipr adapters support an adapter command directed at the device
resource called "Query Resource State". It can be used to retrieve
state information about the resource it is sent to, including the
currently negotiated scsi speed. The adapter interface requires the
IPR_RQTYPE_IOACMD to be set on this command, so we set it if the
command code matches.
