mmc: card: change long_sequential_test time measurements to ktime

Browse source 
Change time measurements in long_sequential_test from jiffies to ktime,
and make the relevant change in test-iosched infrastructure.

In long_sequential_test we measure throughput, and the jiffies resolution
is not sensitive enough for this calculation.
