Bluetooth: hci_qca: fix a NULL-pointer derefence at shutdown
Unlike qca_regulator_init(), qca_power_shutdown() may be called for
QCA_ROME which does not have qcadev->bt_power assigned. Add a
NULL-pointer check before dereferencing the struct qca_power pointer.
Fixes: eba1718717b0 ("Bluetooth: hci_qca: make pwrseq calls the default if available")
