[qemu-s390x] [PATCH v3] s390x: remove direct reference to mem_path globa

From: Igor Mammedov
Subject: [qemu-s390x] [PATCH v3] s390x: remove direct reference to mem_path global form s390x code
Date: Mon, 28 Jan 2019 16:32:38 +0100

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.
