be2net: ignore mac-addr set call for an already programmed mac-addr
An ndo_set_mac_addr() call may be issued for a mac-addr that is already active on an interface. If so, silently ignore the request. Sending such a request to the FW, causes a "mac collision" error. The error is harmless but is avoidable noise in the kernel log.
