net: sched: Fix dump of MPLS_OPT_LSE_LABEL attribute in cls_flower
TCA_FLOWER_KEY_MPLS_OPT_LSE_LABEL is a u32 attribute (MPLS label is
20 bits long).
Fixes the following bug:
$ tc filter add dev ethX ingress protocol mpls_uc \
flower mpls lse depth 2 label 256 \
action drop
$ tc filter show dev ethX ingress
filter protocol mpls_uc pref 49152 flower chain 0
filter protocol mpls_uc pref 49152 flower chain 0 handle 0x1
eth_type 8847
mpls
lse depth 2 label 0 <-- invalid label 0, should be 256
...
Fixes: 61aec25a6db5 ("cls_flower: Support filtering on multiple MPLS Label Stack Entries")
