[PATCH] cxgb4: mark symbols static where possible

[Baoyou Xie]

We get 10 warnings when building kernel with W=1:
drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c:304:5: warning: no previous prototype for 'cxgb4_dcb_enabled' [-Wmissing-prototypes]

drivers/net/ethernet/chelsio/cxgb4/cxgb4_uld.c:442:6: warning: no previous prototype for 'quiesce_rx_uld' [-Wmissing-prototypes]

In fact, these functions are only used in the file in which they are
declared and don't need a declaration, but can be made static.
so this patch marks these functions with 'static'.
