Fix kdb5_util dump.c uninitialized warnings

Some versions of clang report an uninitialized variable warning (which
we treat as an error) in process_k5beta_record.  Due to the if-ladder
style of the function, uninitialized tmpint values can be copied
around in certain error cases, although the garbage values would be
ultimately ignored.  As a minimal fix, initialize the tmpint
variables.
