net: sched: add helpers to handle extended actions

Browse source 
Jump is now the only one using value action opcode. This is going to
change soon. So introduce helpers to work with this. Convert TC_ACT_JUMP.

This also fixes the TC_ACT_JUMP check, which is incorrectly done as a
bit check, not a value check.

Fixes: e0ee84ded7 ("net sched actions: Complete the JUMPX opcode")
