Bluetooth: hci_qca: fix potential GPF
commit 59f90f1 upstream. In qca_power_shutdown() qcadev local variable is initialized by hu->serdev.dev private data, but hu->serdev can be NULL and there is a check for it. Since, qcadev is not used before if (!hu->serdev) return; we can move its initialization after this "if" to prevent GPF.
