Alexey Khoroshilov 95264c8c6a staging: iio: ad7152: Fix deadlock in ad7152_write_raw_samp_freq() 
ad7152_write_raw_samp_freq() is called by ad7152_write_raw() with
chip->state_lock held. So, there is unavoidable deadlock when
ad7152_write_raw_samp_freq() locks the mutex itself.

The patch removes unneeded locking.

Found by Linux Driver Verification project (linuxtesting.org).
