idoutils: fix segfaults on reload with multiple neb modules of the same binary

my bad, the loop did not fetch the correct next address pointer for
free'ing the module list items, resulting in a SIGSEGV.

fixed, but unveils a different problem - multiple handles of a binary
loaded via dlopen() share the same global symbol space which means that
the registered callback functions only work for the first match.

fixes #4033
