i2c: synquacer: fix deferred probing

stable inclusion
from stable-5.10.65
commit 5c68b7795b4c7bdbd54148c9343b5a5edeb476d7
bugzilla: 182361 https://gitee.com/openeuler/kernel/issues/I4EH3U

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=5c68b7795b4c7bdbd54148c9343b5a5edeb476d7

--------------------------------

[ Upstream commit 8d744da2 ]

The driver overrides the error codes returned by platform_get_irq() to
-ENODEV, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the
error codes upstream.
