brcmfmac: free primary net_device when brcmf_bus_start() fails
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. ref.: http://mid.gmane.org/51AD1F22.2080004@wwwdotorg.org Tested-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Hante Meuleman <meuleman@broadcom.com> Reviewed-by: Pieter-Paul Giesberts <pieterpg@broadcom.com> Signed-off-by: Arend van Spriel <arend@broadcom.com> Signed-off-by: John W.
