util/nvmutil rhex: check against sizeof(rnum)

checking against -1 is incorrect, because we specifically want
to ensure that it always read the number of bytes defined by
the size of rnum.

this still covers the case where the return value is -1, and
therefore makes the error handling much stricter.
