device: Fix invalid memory access during Find Included

device: Fix invalid memory access during Find Included

When doing the Find Included Services GATT procedure, the status of the ATT
procedure was being ignored, and in the case of a timeout it is possible to
crash bluetooth with an invalid memory access.

Valgrind log:
