Fix incorrect handles of characteristics descriptors.



The variable descriptorCount is used as an index, and this index is used to set

the handle of the last registered descriptor.



Prior to this fix, descriptorCount was incremented before the handle the update

of the handle of a characteristics.



Short story, all characteristics descriptors handle were equaols to 0 instead

of the actual value.
