firewire: nosy: Replace timeval with timespec64
'struct timeval' uses a 32 bit field for its 'seconds' value which will overflow in year 2038 and beyond. This patch replaces the use of timeval in nosy.c with timespec64 which doesn't suffer from y2038 issue. The code is correct as is - since it is only using the microseconds portion of timeval. However, this patch does the replacement as part of a larger effort to remove all instances of 'struct timeval' from the kernel (that would help identify cases where the code is actually broken).
