Jon Hunter 8407ab4b3e misc: bluedroid_pm: Fix optional GPIOs ...

The function devm_gpiod_get_optional() will return an error code encoded
as a pointer type if the GPIO requested is not found. Therefore, we need
to use the IS_ERR() macro to determine if the GPIO is valid, otherwise
we could incorrectly attempt to dereference an invalid pointer. This bug
was introduced when migrating the bluedroid driver to use the gpiod
functions.
