qcacld-3.0: Fix QDF ASSERT in wma_chan_phy_mode during driver load

Browse source 
If channel received in OEM channel info req is invalid for the
current country code the channel width received will be invalid.
When this invalid channel width is passed to wma_chan_phy_mode,
it cause QDF ASSERT.

To fix this if channel width is invalid set the phy mode invalid.
