Eli Billauer 9b242c4232 char: xillybus: Fix trivial bug with mutex 
commit c002f04c0b upstream.

@unit_mutex protects @unit from being freed, so obviously it should be
released after @unit is used, and not before.

This is a follow-up to commit 282a4b7181 ("char: xillybus: Prevent
use-after-free due to race condition") which ensures, among others, the
protection of @private_data after @unit_mutex has been released.
