Subject: [PATCH] iio: imu: inv_icm45600: Initializes
 inv_icm45600_buffer_postdisable sleep

From: Remi Buisson <remi.buisson@....com>

Fixes: 06674a72cf7a ("iio: imu: inv_icm45600: add buffer support in iio devices")
---
The sleep variable in inv_icm45600_buffer_postdisable could be used without being
assigned in case f error. It must be initialized to 0 by default.
