a cell instance name not related to an array moved a variable that
was used later in the routine to the inside of an if block,
effectively making that variable undefined in most cases.
commit, found that DBTreeFindUse fails to find such uses because
it strips the array delimiters off the name. Fixed the routine
although the routine really should be checking if the use is a
1- or 2- dimensional array and stripping off only the components
expected. The current code will probably fail for cell uses
that have brackets in the name AND are arrayed. Fortunately
this search routine does not appear to be used frequently or in
any critical database functions like netlisting.
