Fixes gcc '-Wunused-but-set-variable' warning:
drivers/bluetooth/hci_qca.c: In function 'qca_controller_memdump':
drivers/bluetooth/hci_qca.c:980:6: warning:
variable 'opcode' set but not used [-Wunused-but-set-variable]
It is never used since commit d841502c79e3 ("Bluetooth: hci_qca: Collect
controller memory dump during SSR"), so remove it.
