tc: don't ignore ok as an action branch

This is what used to happen before:

tc filter add dev tap1 parent ffff: protocol 0xfefe prio 10 \
     u32 match u32 0 0 flowid 1:16 \
     action ife decode allow mark ok

tc -s filter ls dev tap1 parent ffff:
filter protocol [65278] pref 10 u32
filter protocol [65278] pref 10 u32 fh 800: ht divisor 1
filter protocol [65278] pref 10 u32 fh 800::800 order 2048 key ht 800
bkt 0 flowid 1:16
  match 00000000/00000000 at 0
        action order 1: ife decode action pipe
         index 2 ref 1 bind 1 installed 4 sec used 4 sec
         type: 0x0
         Metadata: allow mark
        Action statistics:
        Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0)
        backlog 0b 0p requeues 0

        action order 2: gact action pass
         random type none pass val 0
         index 1 ref 1 bind 1 installed 4 sec used 4 sec
        Action statistics:
        Sent 0 bytes 0 pkt (dropped 0, overlimits 0 requeues 0)
        backlog 0b 0p requeues 0

Note the extra action added at the end..
