Subject: [PATCH 1/2] advansys: Do not byteswap sense_len on big endian

On big endian (e.g. m68k):

    drivers/scsi/advansys.c: In function ‘adv_build_req’:
    drivers/scsi/advansys.c:7806: warning: large integer implicitly truncated to unsigned type

Indeed, adv_scsi_req_q.sense_len is uchar, not __le32, and must never be
byteswapped.

Fixes: 811ddc057aac7228 ("advansys: use DMA-API for mapping sense buffer")
