Bluetooth: qca: fix NULL-deref on non-serdev suspend

In the Linux kernel, the following vulnerability has been resolved:

Bluetooth: qca: fix NULL-deref on non-serdev suspend

Qualcomm ROME controllers can be registered from the Bluetooth line
discipline and in this case the HCI UART serdev pointer is NULL.

Add the missing sanity check to prevent a NULL-pointer dereference when
wakeup() is called for a non-serdev controller during suspend.

Just return true for now to restore the original behaviour and address
the crash with pre-6.2 kernels, which do not have commit e9b3e5b8c657
("Bluetooth: hci_qca: only assign wakeup with serial port support") that
causes the crash to happen already at setup() time.
