Zhang Shurong 5b82e42405 iio: adc: stm32-adc: harden against NULL pointer deref in stm32_adc_probe() 
[ Upstream commit 3a23b384e7e3d64d5587ad10729a34d4f761517e ]

of_match_device() may fail and returns a NULL pointer.

In practice there is no known reasonable way to trigger this, but
in case one is added in future, harden the code by adding the check
