driver: handle a NULL pointer reference on the error path

In the function jailhouse_hypervisor_enable(), jumping to the label
error_unmap results in a call to jailhouse_free_firmware() which
releases hypervisor_mem_res and sets it to NULL. However, the
execution proceeds to the label error_release_memreg and tries to
access hypervisor_mem_res->start, which triggers a NULL pointer
reference.

Fix the problem for explicitly checking against the NULL pointer.

tools: config-create: Use number of int sources for vtd int limit

We were sticking to hardcoded 256 entries there. We now scale better
for systems with more PCI device entries.
