Use __adis_initial_startup instead of adis_initial_startup to
avoid deadlock.
When using adis_initial_startup mutex_lock is called twice,
without releasing it (once inside adis_initial_startup and
once inside adis_enable_irq).

Fixes: 100bfa38c8cb ("iio: imu: adis[16480]: group RW into a single lock in adis_enable_irq()")
