KVM: do not treat noslot pfn as a error pfn
This patch filters noslot pfn out from error pfns based on Marcelo comment: noslot pfn is not a error pfn After this patch, - is_noslot_pfn indicates that the gfn is not in slot - is_error_pfn indicates that the gfn is in slot but the error is occurred when translate the gfn to pfn - is_error_noslot_pfn indicates that the pfn either it is error pfns or it is noslot pfn And is_invalid_pfn can be removed, it makes the code more clean Signed-off-by: Xiao Guangrong <xiaoguangrong@linux.vnet.ibm.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com>
