mem: Remove null-check bypassing in Packet::getPtr

This patch removes the parameter that enables bypassing the null check
in the Packet::getPtr method. A number of call sites assume the value
to be non-null.

The one odd case is the RubyTester, which issues zero-sized
prefetches(!), and despite being reads they had no valid data
pointer. This is now fixed, but the size oddity remains (unless anyone
object or has any good suggestions).

Finally, in the Ruby Sequencer, appropriate checks are made for flush
packets as they have no valid data pointer.
