scsi: libsas: Introduce struct smp_rps_resp
Similarly to sas report general and discovery responses, define the structure struct smp_rps_resp to handle SATA PHY report responses using a structure with a size that is exactly equal to the sas defined response size. With this change, struct smp_resp becomes unused and is removed.
