Fix a serious bug in the behavior of fasdm tool when breaked.

Browse Source 
Under certain conditions it was possible to break (^C) fsadm before actually
resizing filesystem, but lvresize which executed fsadm will think resize
was succesful and shrinks partitions with unresized filesystem on it.

Fix by returning error (1) for this case - this stops lvresize from futher
proceding in resize operation.
