[Qemu-devel] [PATCH v3] s390x: remove direct reference to mem_path global form s390x code

[Igor Mammedov <imammedo@redhat.com>]

I plan to deprecate -mem-path option and replace it with memory-backend,
for that it's necessary to get rid of mem_path global variable.
Do it for s390x case, replacing it with alternative way to enable
1Mb hugepages capability.

To do that, replace qemu_mempath_getpagesize() with qemu_getrampagesize()
which also checks for -mem-path provided RAM.
