PATCH: small corrections to storage/overdata.c and nnrpd/nnrpd.h

[Chris Caputo]

Hi.  Two small patches...

overdata.c:  On success, the overview.fmt file was being left open and the 
"schema" variable was not freed.  Corrected those two things and also made 
it so the "list" variable is freed on failure.

nnrpd.h:  Remove unneeded extern for ARTreadschema().  nnrpd doesn't 
call that anymore.

Thanks,
Chris
