autotest: do not do a blkdiscard during hardware_TrimIntegrity

hardware_StorageFio now does a blkdiscard before running fio to
make sure the test is not impacted by previous tests, but
hardware_TrimIntegrity runs hardware_StorageFio with a read script
to check the read speed/latency before and after trim. We want to
maintain the random data written at the start of the test so we
can verify the trimmed and untrimmed data, so added a parameter to
fio_test to specify whether we want to do the blkdiscard and set it
as False when run within hardware_TrimIntegrity

BUG=chromium:1038166, chromium:994412
TEST=Ran hardware_TrimIntegrity
