mlxsw: spectrum_flower: validate control flags
This driver currently doesn't support any control flags.
Use flow_rule_has_control_flags() to check for control flags,
such as can be set through `tc flower ... ip_flags frag`.
In case any control flags are masked, flow_rule_has_control_flags()
sets a NL extended error message, and we return -EOPNOTSUPP.
Only compile-tested.
