memory: use mr->ram_addr in "is this RAM?" assertions

mr->terminates alone doesn't guarantee that we are looking at a RAM region.
mr->ram_addr also has to be checked, in order to distinguish RAM and I/O
regions.

So, do the following:

1) add a new define RAM_ADDR_INVALID, and test it in the assertions
instead of mr->terminates

2) IOMMU regions were not setting mr->ram_addr to a bogus value, initialize
it in the instance_init function so that the new assertions would fire
for IOMMU regions as well.
