[PATCH] misc scsi bits
Various small bits that make SCSI work well with REQ_BLOCK_PC.
o Use ->errors as the scsi status byte for REQ_BLOCK_PC
o Always call end_io completion, even if 0 sectors, as long as the
status is good. Otherwise we risk hanging this device if a
REQ_BLOCK_PC user command didn't specify a transfer size for a command
that did.
o Remove bouncing checks in scsi_merge for REQ_BLOCK_PC, bio_map_user()
correctly bounces pages now.
o Decrement req->data_len, it's our residual data count.
o sr/sd: set right transfer and underflow size.
