brcmfmac: use bssidx from struct brcmf_if for bsscfg specific commands

The firmware interface has functions to send bsscfg specific commands
to the device. These functions currently have a bssidx parameter, but
that same information is stored in struct brcmf_if, which is in the
private data of the net_device parameter.
