tests/qtest/ahci-test.c: Calculate iso_size with 64-bit arithmetic 

Coverity notes that when calculating the 64-bit iso_size value in
ahci_test_cdrom() we actually only do it with 32-bit arithmetic.
This doesn't matter for the current test code because nsectors is
always small; but adding the cast avoids the coverity complaints.
