xen: move max_pfn in xen_memory_setup() out of function scope

Browse source

[ Upstream commit 43dc2a0f47 ]

Instead of having max_pfn as a local variable of xen_memory_setup(),
make it a static variable in setup.c instead. This avoids having to
pass it to subfunctions, which will be needed in more cases in future.

Rename it to ini_nr_pages, as the value denotes the currently usable
number of memory pages as passed from the hypervisor at boot time.
