xen: x86: mark xen_find_pt_base as __init
gcc-4.6 causes a harmless link-time warning:
WARNING: vmlinux.o(.text.unlikely+0x48e): Section mismatch in reference from the function xen_find_pt_base() to the function .init.text:m2p()
The function xen_find_pt_base() references
the function __init m2p().
This is often because xen_find_pt_base lacks a __init
annotation or the annotation of m2p is wrong.
Newer compilers inline this function, so it never shows up, but marking
it __init is the right way to avoid the warning.
Fixes: 70e61199559a ("xen: move p2m list if conflicting with e820 map")
