An incorrect sizeof() is being used, sizeof(rhub->ports) is not
correct, it should be sizeof(*rhub->ports).  This bug did not
cause any issues because it just so happens the sizes are the same.

Addresses-Coverity: ("Sizeof not portable (SIZEOF_MISMATCH)")
Fixes: bcaa9d5c5900 ("xhci: Create new structures to store xhci port information")
