brcmfmac: feature check for multi-scheduled scan fails on bcm4343x devices
The firmware feature check introduced for multi-scheduled scan turned out to be failing for bcm4343{0,1,8} devices resulting in a firmware crash. The reason for this crash has not yet been root cause so this patch avoids the feature check for those device as a short-term fix.
