tun: fix missing dropped counter in tun_xdp_act
The commit 8ae1aff0b331 ("tuntap: split out XDP logic") includes
dropped counter for XDP_DROP, XDP_ABORTED, and invalid XDP actions.
Unfortunately, that commit missed the dropped counter when error
occurs during XDP_TX and XDP_REDIRECT actions. This patch fixes
this issue.
