Peter Krempa 9d039863e2 qemu: block: Remove 'active-write' bitmap even if there are no bitmaps to merge
The 'libvirt-tmp-activewrite' bitmap is added during the 'pivot'
operation of block copy and active layer block commit operations
regardless of whether there are any bitmaps to merge, but was not
removed unless a bitmap was merged. This meant that subsequent attempts
to merge into the same image would fail.

Fix it by checking whether the 'libvirt-tmp-activewrite' would be used
by the code and don't skip the code which would delete it.

This is a regression introduced when we switched to the new code for
block commit in <20a7abc2d2d> and for block copy in <7bfff40fdfe5>. The
actual bug originates from <4fa8654ece>.
