[PATCH] staging: wfx: fix scan with WFM200 and WW regulation

[Jerome Pouiller <Jerome.Pouiller@silabs.com>]

From: Riccardo Ferrazzo <rferrazzo@came.com>

Some variants of the WF200 disallow active scan on channel 12 and 13.
For these parts, the channels 12 and 13 are marked IEEE80211_CHAN_NO_IR.

However, the beacon hint procedure was removing the flag
IEEE80211_CHAN_NO_IR from channels where a BSS is discovered. This was
making subsequent scans to fail because the driver was trying active
scans on prohibited channels.
