KVM: MMU: Eliminate pointless temporary 'ac'
'ac' essentially reconstructs the 'access' variable we already have, except for the PFERR_PRESENT_MASK and PFERR_RSVD_MASK. As these are not used by callees, just use 'access' directly. Reviewed-by: Xiao Guangrong <xiaoguangrong@linux.vnet.ibm.com> Signed-off-by: Avi Kivity <avi@redhat.com>
