firewire: nosy: Replace timeval with timespec64
32 bit systems using 'struct timeval' will break in the year 2038, so we replace the code appropriately. However, this driver is not broken in 2038 since we are using only the microseconds portion of the current time. This patch replaces timeval with timespec64.
