Remove unnecessary overload for hash<>

The overload for pointers in hash tables was applied in normal
usage of schur_ordering.cc. However, the tests did not include the
overload since they only included collections_port.h. As a result,
the routines in schur_ordering.cc were using a different hash
function than that inside the tests.

The fix is to remove the specialization. If this breaks one of the
compiler configurations, we will find a workaround at that time.
