[PATCH 1/3] bsg: Make job reply size different than SCSI_SENSE_BUFFERSIZE

[Avri Altman]

The size of the bsg job reply was set to SCSI_SENSE_BUFFERSIZE back then
while it was part of the bsg_command. However, for the scsi transport
that uses it, it does not carry the scsi sense information.

Rename it to clarify this point, and while at it, make it a little bit
larger, so it'll be able to carry some useful information,
e.g. ufs descriptors, should be needed.
