ktime: Use macro NSEC_PER_USEC where appropriate
We've got the macro NSEC_PER_USEC defined in header file
include/linux/time.h. To make the code decent, this patch
replaces the immediate number 1000 to convert bewteen a
time value in microseconds and one in nanoseconds with the
macro NSEC_PER_USEC.
