wlcore: use boottime for fw time sync
Using getnstimeofday()/timespec_to_ns() causes an overflow on 32-bit architectures in 2038, and may suffer from time jumps due to settimeofday() or leap seconds. I don't see a reason why this needs to be UTC, so either monotonic or boot time would be better here. Assuming that the fw time keeps running during suspend, boottime is better than monotonic, and ktime_get_boot_ns() will also save the additional conversion to nanoseconds.
