Alexandru Ardelean 5efb3f9140 iio: dac: ad5592r: fix unbalanced mutex unlocks in ad5592r_read_raw()
commit 65afb0932a upstream.

There are 2 exit paths where the lock isn't held, but try to unlock the
mutex when exiting. In these places we should just return from the
function.

A neater approach would be to cleanup the ad5592r_read_raw(), but that
would make this patch more difficult to backport to stable versions.

Fixes 56ca9db862bf3: ("iio: dac: Add support for the AD5592R/AD5593R ADCs/DACs")
