iio: frequency: adf4377: replace mutex_lock/unlock with guard(mutex)()

Browse source

Replace manual mutex_lock()/mutex_unlock() calls with guard(mutex)() from
cleanup.h.

Using guard(mutex)() from cleanup.h allows the compiler to enforce lock
release on every exit path, eliminating the error-prone manual lock/unlock
pattern and the goto-based exit labels that existed in adf4377_get_freq()
and adf4377_set_freq(). This reduces the chance of lock imbalance bugs.
