The crc32 test function measures the elapsed time in nanoseconds, but
uses 'struct timespec' for that. We want to remove timespec from the
kernel for y2038 compatibility, and ktime_get_ns() also helps make the
code simpler here.
It is also slightly better to use monontonic time, as we are only
interested in the time difference.
