KVM: MMU: Fix build warnings in walk_addr_generic()

On 3.0-rc1 I get

In file included from arch/x86/kvm/mmu.c:2856:
arch/x86/kvm/paging_tmpl.h: In function ‘paging32_walk_addr_generic’:
arch/x86/kvm/paging_tmpl.h:124: warning: ‘ptep_user’ may be used uninitialized in this function

arch/x86/kvm/paging_tmpl.h:124: warning: ‘ptep_user’ may be used uninitialized in this function

caused by 6e2ca7d1802bf8ed9908435e34daa116662e7790. According to Takuya
Yoshikawa, ptep_user won't be used uninitialized so shut up gcc.
