r8169: give RTL_GIGA_MAC_VER_EXTENDED a distinct value

RTL_GIGA_MAC_VER_EXTENDED implicitly follows
RTL_GIGA_MAC_VER_LAST = RTL_GIGA_MAC_NONE - 1, so it has the same value
as RTL_GIGA_MAC_NONE.

rtl_init_one() therefore sends unknown chips through extended detection.
If TX_CONFIG_V2 reads as zero, they are misidentified as RTL9151AS
instead of being rejected.

Give RTL_GIGA_MAC_VER_EXTENDED a distinct value. It is only a detection
marker and is never stored in tp->mac_version.

Found by Clang's -Wduplicate-enum and verified with a QEMU stub.
