Subjectfsi: use put_device to release resource on error path
Date
In the function fsi_slave_init, kfree is used to release slave if error
occurs during set smode. Some fields of slave will not be released.
Resulting in memory leak. Instread, put_device should be used to
correctly release resources.

Fixes: d1dcd6782576("fsi: Add cfam char devices")
