[PATCH v2] iio: imu: inv_icm45600: Initializes inv_icm45600_buffer_postdisable sleep

[Remi Buisson via B4 Relay]

From: Remi Buisson <remi.buisson@xxxxxxx>

The sleep variable in inv_icm45600_buffer_postdisable could be used without
being assigned in case of error. It must be initialized to 0 by default.

Fixes: 06674a72cf7a ("iio: imu: inv_icm45600: add buffer support in iio devices")
Smatch static checker warning:

	drivers/iio/imu/inv_icm45600/inv_icm45600_buffer.c:377 inv_icm45600_buffer_postdisable()
	error: uninitialized symbol 'sleep'.
