[PATCH] xen PVonHVM: fix compile warning in init_hvm_pv_info

[Olaf Hering]

After merging the xen-two tree, today's linux-next build (x86_64
allmodconfig) produced this warning:

arch/x86/xen/enlighten.c: In function 'init_hvm_pv_info':
arch/x86/xen/enlighten.c:1617:16: warning: unused variable 'ebx' [-Wunused-variable]
arch/x86/xen/enlighten.c:1617:11: warning: unused variable 'eax' [-Wunused-variable]

Introduced by commit 9d02b43dee0d ("xen PVonHVM: use E820_Reserved area
for shared_info").
