qemuCheckpointDiscardBitmaps: Reopen images for bitmap modifications

Browse Source 
Qemu's bitmap APIs don't reopen the appropriate images read-write for
modification. It's libvirt's duty to reopen them via blockdev-reopen
if we wish to modify the bitmaps.

Use the new helpers to reopen the images for bitmap manipulation.
