  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: b600bd7eb3335 ("iio: adis: do not disabe IRQs in 'adis_init()'")
