crypto: msm: Fix counter IV calculation

CTR mode operation fails due to incorrect CNTR IV  returned
for large size packets.  For large packets, adding the number
of crypto blocks (16 byte chunks) to the CNTR_IV3 register
sometimes results in oevrflowing the register and hence an
incorrect value is reported back.

The counter IV for CTR/XTS mode is calculated incorrectly.
Th fix is to account for roll over scenarios. when the updated
counter value exceeds 0xFFFFFFFF.
