mirror: Handle failures in tmp mirror used when up-converting.

Browse Source 
Failures in the temporary mirror used when up-converting cause dmeventd
to issue 'lvconvert --repair' on the sub-LV, <lv_name>_mimagetmp_?.  The
'lvconvert' command refuses to deal with this sub-LV outright - it
expects to be given the name of the top-level LV.  So, just like we do
with mirrored logs, we strip-off the portion of the name that is not
the top-level LV and issue the command on the top-level LV instead.
