driver: iio: add missing checks on iio_info's callback access
8763cdb 
Some callbacks from iio_info structure are accessed without any check, so
if a driver doesn't implement them trying to access the corresponding
sysfs entries produce a kernel oops such as:

If an error occurs in the probe() function, we should remove the polling
timer that was alarmed earlier, otherwise the timer is called with
arguments that are already freed, which results in a crash.
