When a beacon from the AP contains only the ECSA IE, and not a CSA IE
as well, this ECSA IE is not considered for calculating the CRC and
the beacon might be dropped as not being interesting. This is clearly
wrong, it should be handled and the channel switch should be executed.

Fix this by including the ECSA IE ID in the bitmap of interesting IEs.
