mlxsw: spectrum_router: Return an error for non-default FIB rules
Since commit 9776d32537d2 ("net: Move call_fib_rule_notifiers up in
fib_nl_newrule") it is possible to forbid the installation of
unsupported FIB rules.
Have mlxsw return an error for non-default FIB rules in addition to the
existing extack message.
Example:
# ip rule add from 198.51.100.1 table 10
Error: mlxsw_spectrum: FIB rules not supported.
Note that offload is only aborted when non-default FIB rules are already
installed and merely replayed during module initialization.
