[PATCH] Fix leaked config override mempool.

[PATCH] Fix leaked config override mempool.

[Milan Broz]

Fix leaked config override mempool.

pvs --config 'global { units = "<" }'
  Invalid units specification
  Updated config file invalid. Aborting.

causes in old code
    Segmentation fault
and now memory leak :-)

Fix it by properly releasing overrided config in lvm_run_command
if refresh_toolcontext() fails.
