Not all descriptors where discovered in some cases

While discovering descriptors, when handles are not numbered
sequentially, the discovery stopped as soon as "no attribute in given
range found" error is received. However, there could be more
characteristics pending. As a result, descriptors for those
characteristics where never discovered.
