tty-hvsi_lib: Deletion of an unnecessary check before the function call "tty_kref_put"

Browse source 
The tty_kref_put() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
