Previous commit 7ef5e54e2e28884a04dc800657967b891239e933 caused
module probe failure on 32-bit systems, dmesg showed
Unknown symbol __moddi3
This was caused by the modulo operation 'gethrtime() % tqs->stqs_count'
in the committed code. Instead of implementing __moddi3 for all 32-bit
systems, Behlendorf advised we can just cast the return value of
gethrtime() into a uint64_t, since gethrtime does not return negative
value on all circumstances we need not care about the potential overflow.
