Gopal Tiwari 006159faf9 Bluetooth: Fix null pointer dereference in amp_read_loc_assoc_final_data 
[ Upstream commit e8bd76ede1 ]

kernel panic trace looks like:

hcon->amp_mgr seems NULL triggered kernel panic in following line inside
function amp_read_loc_assoc_final_data

        set_bit(READ_LOC_AMP_ASSOC_FINAL, &mgr->state);

Fixed by checking NULL for mgr.
