tty: audit: remove unused variable
While building with W=1 we were getting build warning: drivers/tty/tty_audit.c:149:16: warning: variable 'sessionid' set but not used The local variable sessionid was only assigned the value of current->sessionid but was never reused. On further inspection it turned out that there is no need of audit_get_loginuid() also.
