This is also fixing the bytecode that is generated for:

nft add rule ip filter output ct direction reply counter

ip filter output 54 53
  [ ct load direction => reg 1 ]
  [ bitwise reg 1 = (reg=1 & 0x00000001 ) ^ 0x00000000 ]
  [ cmp neq reg 1 0x00000000 ]
  [ counter pkts 0 bytes 0 ]

and the output:

ct direction & reply != original counter packets 0 bytes 0

which doesn't obviously work.

To this:

ip filter output 57 56
  [ ct load direction => reg 1 ]
  [ cmp eq reg 1 0x00000001 ]
  [ counter pkts 0 bytes 0 ]

Feel free to push it. Thanks!
