[SCSI] kill scsi_rety_command

Browse Source 
scsi_retry_command only has a single caller, so there is no point
in having this function.  Additionally the memset of the sense
buffer it does is entirely superflous as scsi_request_fn already
calls scsi_init_cmd_errh to perform this memset before the command
is reissued.
