Fix issue reported by Coverity.
Coverity ID 13255: Overflowed return value: The return value will be too
small or even negative, likely resulting in unexpected behavior in a
caller that uses the return value. In rte_mem_virt2phy: An integer
overflow occurs, with the overflowed value used as the return value of
the function
Fixes: 3097de6e6bfb ("mem: get physical address of any pointer")
