[PATCH v1 04/10] qemu_domain.c: simplify qemuDomainGetMemoryModuleSizeAlignment()

[Daniel Henrique Barboza]

The function is no longer used for ppc64 alignment. This allow us
to exclude the 'def' argument and simplify its usage. Let's also
make it clearer in the comment that the function is now returning
x86 specific values.
