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.

Fixes: c3ab4354
