x86/xen: fix memblock_reserve() usage on PVH
The current usage of memblock_reserve() in init_pvh_bootparams() is done before
the .bss is zeroed, and that used to be fine when
memblock_reserved_init_regions implicitly ended up in the .meminit.data
section. However after commit 73db3abdca58c memblock_reserved_init_regions
ends up in the .bss section, thus breaking it's usage before the .bss is
cleared.
Move and rename the call to xen_reserve_extra_memory() so it's done in the
x86_init.oem.arch_setup hook, which gets executed after the .bss has been
zeroed, but before calling e820__memory_setup().
Fixes: 73db3abdca58c ("init/modpost: conditionally check section mismatch to __meminit*")
