iio: imu: adis: rename txrx_lock -> state_lock

Browse Source 
The lock can be extended a bit to protect other elements that are not
particular to just TX/RX. Another idea would have been to just add a new
`state_lock`, but that would mean 2 locks which would be redundant, and
probably cause more potential for dead-locks.

What will be done in the next patches, will be to add some unlocked
versions for read/write_reg functions.
