[PATCH 21/25] dept: Apply timeout consideration to hashed-waitqueue wait

[Gwan-gyeong Mun]

From: Byungchul Park <byungchul.park at lge.com>

Now that CONFIG_DEPT_AGGRESSIVE_TIMEOUT_WAIT was introduced, apply the
consideration to hashed-waitqueue wait, assuming an input 'ret' in
___wait_var_event() macro is used as a timeout value.
