Don't fail qemu driver intialization if we can't determine hugepage size

Otherwise we fail like

  libvirt version: 1.2.7, package: 6 (root 2014-08-08-16:09:22 bogon)
  virAuditOpen:62 : Unable to initialize audit layer: Protocol not supported
  virFileGetDefaultHugepageSize:2958 : internal error: Unable to parse /proc/meminfo
  virStateInitialize:749 : Initialization of QEMU state driver failed: internal error: Unable to parse /proc/meminfo
  daemonRunStateInit:922 : Driver state initialization failed

if the data can't be determined.
