using iSCSI URL test_inquiry_alloc is failing.

[sssharma10]

test case checking for getting same inquiry data from SCSI server is failing for iSCSI url path.
In case if I pass device directly with same setup test case is passing but when run test suite with iSCSI URL it is failing.
We are not recalculating datain size if we got residual data.
Attaching patch can you verify it also I have not tested its impact on other test cases.
