mlxsw: spectrum_fid: Update dummy FID index
When using a tc flower action of egress mirred redirect, the driver adds an implicit FID setting action. This implicit action sets a dummy FID to the packet and is used as part of a design for trapping unmatched flows in OVS. While this implicit FID setting action is supposed to be a NOP when a redirect action is added, in Spectrum-2 the FID record is consulted as the dummy FID index is an 802.1D FID index and the packet is dropped instead of being redirected. Set the dummy FID index value to be within 802.1Q range. This satisfies both Spectrum-1 which ignores the FID and Spectrum-2 which identifies it as an 802.1Q FID and will then follow the redirect action.
