Any return value from gpiod_get_optional() other than a pointer to a
GPIO descriptor or a NULL-pointer is an error and the driver should
abort probing. That being said: commit 56d074d2 ("Bluetooth: hci_qca:
don't use IS_ERR_OR_NULL() with gpiod_get_optional()") no longer sets
power_ctrl_enabled on NULL-pointer returned by
devm_gpiod_get_optional(). Restore this behavior but bail-out on errors.
While at it: also bail-out on error returned when trying to get the
"swctrl" GPIO.
