cxgb4: make the array match_all_mac static, makes object smaller

Don't populate the array match_all_mac on the stack but instead it
static const. Makes the object code smaller by 75 bytes.

Before:
   text    data     bss     dec     hex filename
  46701    8960      64   55725    d9ad ../chelsio/cxgb4/cxgb4_filter.o

After:
   text    data     bss     dec     hex filename
  46338    9120     192   55650    d962 ../chelsio/cxgb4/cxgb4_filter.o

(gcc version 10.2.0)
