Currently it is generically setting the status code to FC_CMD_RECOVERY for all error types. This results in DID_BUS_BUSY errors being returned to the scsi-ml. DID_BUS_BUSY errors indicate "BUS stayed busy through time out period" according to scsi.h. Many of the error reported by fc_rcp_recovery() are pkt errors. Here we update fc_fcp_recovery to use better host byte codes. With certain FAST FAIL flags set DID_BUS_BUSY and DID_ERROR will have different behaviors this was causing dm multipath to fail quickly in some cases where a retry would be a better action.
