leds: netxbig: Fix GPIO descriptor leak in error paths

Browse source

[ Upstream commit 03865dd8af ]

The function netxbig_gpio_ext_get() acquires GPIO descriptors but
fails to release them when errors occur mid-way through initialization.
The cleanup callback registered by devm_add_action_or_reset() only
runs on success, leaving acquired GPIOs leaked on error paths.

Add goto-based error handling to release all acquired GPIOs before
returning errors.
