Subject: [PATCH 11/35] block: remove bdrv_dirty_bitmap_make_anon

O-Subject: [RHEL8/rhel qemu-kvm PATCH 01/24] block: remove bdrv_dirty_bitmap_make_anon
Bugzilla: 1518989

From: Paolo Bonzini <pbonzini@redhat.com>

All this function is doing will be repeated by
bdrv_do_release_matching_dirty_bitmap_locked, except
resetting bm->persistent.  But even that does not matter
because the bitmap will be freed.
