mlxsw: spectrum_matchall: Perform priority checks earlier
Perform the priority check earlier in the function instead of repeating
it for every action. This fixes a bug that allowed matchall rules with
sample action to be added in front of flower rules on egress.
Fixes: 54d0e963f683 ("mlxsw: spectrum_matchall: Add support for egress sampling")
