tc: f_u32: Fill in 'linkid' provided by user

Currently, 'linkid' input by the user is parsed but 'handle' is appended to the netlink message.

# tc filter add dev enp1s0f1 protocol ip parent ffff: prio 99 u32 ht 800: \
	order 1 link 1: offset at 0 mask 0f00 shift 6 plus 0 eat match ip \
	protocol 6 ff

resulted in:
filter protocol ip pref 99 u32 fh 800::1 order 1 key ht 800 bkt 0
  match 00060000/00ff0000 at 8
    offset 0f00>>6 at 0  eat

This patch results in:
filter protocol ip pref 99 u32 fh 800::1 order 1 key ht 800 bkt 0 link 1:
  match 00060000/00ff0000 at 8
    offset 0f00>>6 at 0  eat
