MLK-21493 brcmfmac: move .brcmf_bus_preinit() after changing bus state

Moving the brcmf_bus_preinit() call allows the bus code to do some
required initialization before handling firmware control messages.

.brcmf_bus_preinit() already is called in .brcmf_bus_started() when
bus is ready. So remove it from .brcmf_c_preinit_dcmds().
