brcmfmac: free primary net_device when brcmf_bus_start() fails

Browse source 
When initialization within brcmf_bus_start() fails on steps
before the brcmf_net_attach() the net_device for the primary
interface needs to be freed.

This patch resolves a panic during kernel boot as reported
by Stephen Warren.
