Bluetooth: hci_intel: Fix null gpio desc pointer dereference

gpiod_get_optional can return either ERR_PTR or NULL pointer.
NULL case is not tested and then dereferenced later in desc_to_gpio.
Fix this by using non optional version which returns ERR_PTR in any
error case (this is not an optional gpio).
Use the same non optional version for the host-wake gpio.
