xdp: remove redundant argument to trace_xdp_redirect

Browse Source 
Supplying the action argument XDP_REDIRECT to the tracepoint xdp_redirect
is redundant as it is only called in-case this action was specified.

Remove the argument, but keep "act" member of the tracepoint struct and
populate it with XDP_REDIRECT.  This makes it easier to write a common bpf_prog
processing events.
