scsi: move unmap error checking to the complete callback
This will help to account the operation in the following commit. The difference is that we don't call scsi_disk_req_check_error() before the 1st discard iteration anymore. That function also checks if the request is cancelled, however it shouldn't get canceled until it yields in blk_aio() functions anyway. Same approach is already used for emulate_write_same.
