scsi: bsg: Pass reply_len to bsg_setup_queue() to fit UFS ARPMB replies
bsg-lib allocates a 96-byte (SCSI_SENSE_BUFFERSIZE) reply buffer per
job, but struct ufs_rpmb_reply is 104 bytes: a 40-byte struct
ufs_bsg_reply followed by a 64-byte EHS. When an Advanced RPMB command
returns an EHS, ufshcd_advanced_rpmb_req_handler() copies it right after
the 40-byte header and writes 8 bytes past the end of the buffer.
Let each BSG transport pass its reply buffer size to bsg_setup_queue()
and have ufs_bsg request sizeof(struct ufs_rpmb_reply), so the full
reply reaches user space. Other transports keep SCSI_SENSE_BUFFERSIZE.
Fixes: 6ff265fc5ef6 ("scsi: ufs: core: bsg: Add advanced RPMB support in ufs_bsg")
