The Coverity checker noted that we'll anyway Oops later when we ran into
this condition - and the error check didn't prevent that.
Considering that the error condition shouldn't be possible, and we are
not able to handle it easily, this patch simply removes the pointless
error check.
This converts tgt to use the data buffer accessors to reduce the size
of the scsi_data_buffer patch for tgt, which will be merged later.
