This fixes bdrv_reopen() calls like the following one:
qemu-io -c 'open -o overlap-check.template=all /tmp/test.qcow2' \
-c 'reopen -o overlap-check=none'
The approach taken so far would result in an options QDict that has both
"overlap-check.template=all" and "overlap-check=none", which obviously
conflicts. In this case, the old option should be overridden by the
newly specified option.
