[Qemu-devel] [PULL 02/10] s390x: remove direct reference to mem_path global from s390x code

[Cornelia Huck <cohuck@redhat.com>]

From: 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.

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