qcacld-3.0: Avoid pkt drop in DFS CAC for SAP dual band mode

When dual band mode for SAP is enabled from UI, the packet
for 2G SAP will be dropped before dfs cac finishes.

Adjust channel check to avoid pkt drop in lim_handle80211_frames.
  1 non-sbs mode, bypass 2g channel packet
  2 sbs mode, bypass non dfs channel packet
