[SCSI] scsi_dh: Implement match callback function
Some device handler types are not tied to the vendor/model but rather to a specific capability. Eg ALUA is supported if the 'TPGS' setting in the standard inquiry is set. This patch implements a 'match' callback for device handler which supersedes the original vendor/model lookup and implements the callback for the ALUA handler.
