[PATCH 4/5] P2P: Fall-back to no VHT when starting AP/P2P GO

[Ilan Peer]

From: Avraham Stern <avraham.stern at intel.com>

In cases that the bandwidth is not set when starting an AP/P2P GO,
the code tries to use 160MHz or 80MHz channels. As a result, the
AP/P2P GO configuration is set to use these channel widths even if
they are not available, which may results in failing to start the
AP/P2P GO.

Fix this by changing the AP/P2P GO configuration not to use
VHT channels when they are not available. In this case the AP/P2P GO
will use a 40MHz channel if available, or a 20MHz channel if this is
the maximum available width.
