Currently only 1 scan can be performed on per phy level at a time in
driver. Due to this, if via other underlying phy, a scan request is sent,
kernel returns -EBUSY. And then hostapd would try to set the interface in
station mode if it was originally in AP mode and retry sending a scan
request. However, this behaviour is expected in case of multi link
operation and hence there is no need to switch the mode as such.

Hence, add logic to not change the NL mode if kernel returns -EBUSY during
multi link AP operation. The caller can accordingly decide and if needed,
it can re-schedule a scan request after some time.

This does not compile without patch 2/4, so I cannot apply this before
the items on patch 2 are addressed.


Sure, will address 2/4 comments and send 2/4 and 3/4 in next version.
