scsi: ufs: ufshcd-pltfrm: Fix deferred probing
[ Upstream commit 339c9b63cc7ce779ce45c675bf709cb58b807fc3 ]
The driver overrides the error codes returned by platform_get_irq() to
-ENODEV, so if it returns -EPROBE_DEFER, the driver would fail the probe
permanently instead of the deferred probing. Propagate the error code
upstream as it should have been done from the start...
