be2net: Provide an alternate way to read pf_num for BEx chips
The driver gets the pf_num for Skyhawk and Lancer using GET_FUNC_CONFIG FW command. But since that command is not supported in BEx, we need to get it from some other command. Otherwise TPE recovery would fail since all NIC PFs would end up with a func num of 0. There's a pci function number field in the response of GET_CNTL_ATTRIBUTES command that can be read to get the same info for BEx adapters.
