[PATCH 4.9 008/212] ath9k: release allocated buffer if timed out

[Greg Kroah-Hartman]

From: Navid Emamdoost <navid.emamdoost@xxxxxxxxx>

[ Upstream commit 728c1e2a05e4b5fc52fab3421dce772a806612a2 ]

In ath9k_wmi_cmd, the allocated network buffer needs to be released
if timeout happens. Otherwise memory will be leaked.
