Fix using the wrong start handle for Desc. Discovery
Fix using the wrong start handle for Desc. Discovery

When doing the Descriptor Discovery procedure, the wrong starting
handle was being used (the characteristic value handle). This is what
the spec mandates:

"The Attribute Protocol Find Information Request shall be used with the
Starting Handle set to the handle of the specified characteristic value
+ 1 and the Ending Handle set to the ending handle of the specified
characteristic."
