time: Prevent 32 bit overflow with set_normalized_timespec()
set_normalized_timespec() nsec argument is of type long. The recent
timekeeping changes of ktime_get_ts() feed
ts->tv_nsec + tomono.tv_nsec + nsecs
to set_normalized_timespec(). On 32 bit machines that sum can be
larger than (1 << 31) and therefor result in a negative value which
screws up the result completely.
Make the nsec argument of set_normalized_timespec() s64 to fix the
problem at hand. This also prevents similar problems for future users
of set_normalized_timespec().
