[RFC 1/7] mac80211: Add check for napi handle before WARN_ON
From: Rakesh Pillai
Date: Tue Jul 21 2020 - 13:14:53 EST
The function ieee80211_rx_napi can be now called
from a thread context as well, with napi context
being NULL.
Hence add the napi context check before giving out
a warning for softirq count being 0.
Tested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.1-01040-QCAHLSWMTPLZ-1
