[Qemu-devel] [PULL 1/7] block: remove bdrv_dirty_bitmap_make_anon

[John Snow <jsnow@redhat.com>]

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.
