Naveen Kumar Chaudhary c12c4cae0c time: Fix off-by-one in settimeofday() usec validation ...

[ Upstream commit ce4abda5e1 ]

The validation check uses '>' instead of '>=' when comparing tv_usec
against USEC_PER_SEC, allowing the value 1000000 through. After
conversion to nanoseconds (*= 1000), this produces tv_nsec ==
NSEC_PER_SEC, violating the timespec invariant that tv_nsec must be
less than NSEC_PER_SEC.

Use '>=' to reject tv_usec values that are not in the valid range of
0 to 999999.
