[PATCH] Add missing error reporting when loading mac filter config for QEMU

["Daniel P. Berrange" <berrange@xxxxxxxxxx>]

If the 'mac_filter' configuration parameter is enabled, and there
is a failure to enable filtering, no error is reported back to
the caller. Also fix some bogus whitespace indentation for
hugetlbfs_mount

* src/qemu/qemu_conf.c: Add missing error reporting
