Temporarily disable PMP/MEM errors in icache testbench

Browse source 
This allows tests to run to completion. Unfortunately, the core agent
currently has a bug in how it handles errors (if a sequence item
terminates with an error and is followed by a 'req' sequence item, the
test hangs).

I'll fix that in a separate patch soon (and revert this commit), but
don't want the memory agent changes to depend on the fix.
