fix(ble/bluedroid): set REQ_WAITING before GATTC service-change rediscovery

Browse Source 
When service change cancels in-progress discovery, bta_gattc_disc_cmpl()
re-triggers discovery without marking auto_update as REQ_WAITING. If a
client command is queued in p_q_cmd, bta_gattc_start_discover() refuses
to restart and the command is never dispatched.


(cherry picked from commit 13926bb9bc)
