LU-17000 utils: Initialize 'idgot' time before using

LU-17000 utils: Initialize 'idgot' time before using

In case there is an error reading the contents of permission
file. gettimeofday() is correctly not called on 'idgot'.
However, this means that 'idgot' timeval is left uninitialized.
This patch Initialize 'idgot' timeval to 0 so that in case as
above the value is printed as zero and not garbage.
