systemc: Use sc_assert to check the number of interfaces.
The sc_port code had been using the .at() function of the vector class,
but when that failed it threw an exception, and it was very difficult
to tell where the exception came from from how gem5 crashed. This
change switches to sc_assert (the systemc version of assert) which
makes the cause/location of failures much more obvious.
