wlan: Fix NULL pointer crash due to a race in accessing ROC context. In wlan_hdd_cfg80211_cancel_remain_on_channel API "is_pending_roc_cancelled" variable is not protected with a mutex. ROC context can become NULL in wlan_hdd_remain_on_channel_callback API when this gets executed in McThread context. Due to this accessing "is_pending_roc_cancelled" variable causes panic. Fix this by aquiring mutex lock. Change-Id: I950d77b31b33bd7eec963ce4d4119373faa7447f CRs-Fixed: 875771
