If the build environment hasn't 'linux/tc_act/tc_pedit.h',
compiler will use needed structs defined in mlx5_flow_tcf.c.
However, there is a zero-size array defined in one struct and
ISO C forbids this when -Wpedantic is set by debug mode.
Simply put __extension__ keyword before the struct in question.
Fixes: e696b2051c8c ("net/mlx5: rewrite IP address UDP/TCP port by E-Switch")
