net: gptp: Fix type mismatch calculation error in gptp_mi 

NSEC_PER_SEC is an unsigned integer macro. Thus, -NSEC_PER_SEC will be
treated as unsigned integer as well which lead to calculation error on
64bits integer variables. Added the correct type casting into the formula
to fix the calculation error.
