[PATCH 5.15.y] iio: light: ltr501: Power down chip if request irq fails

[Sasha Levin <sashal@kernel.org>]

From: Esben Haabendal <esben@geanix.com>

[ Upstream commit 8a9bcd587d7d768e6c8e9fff88bb89645e412731 ]

In case devm_request_threaded_irq() failed, we were leaving the chip
powered instead of powering it down again. Power down the chip switching
ALS and PS modes to standby.
