Clang warns when one enumerated type is implicitly converted to another.

drivers/net/ethernet/chelsio/cxgb4/cxgb4_dcb.c:390:4: warning: implicit
conversion from enumeration type 'enum cxgb4_dcb_state' to different
enumeration type 'enum cxgb4_dcb_state_input' [-Wenum-conversion]
                        IEEE_FAUX_SYNC(dev, dcb);
                        ^~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/chelsio/cxgb4/cxgb4_dcb.h:70:10: note: expanded
from macro 'IEEE_FAUX_SYNC'
                                            CXGB4_DCB_STATE_FW_ALLSYNCED);
                                            ^~~~~~~~~~~~~~~~~~~~~~~~~~~~

Use the equivalent value of the expected type to silence Clang while
resulting in no functional change.

CXGB4_DCB_STATE_FW_ALLSYNCED = CXGB4_DCB_INPUT_FW_ALLSYNCED = 3

Luckily these 2 enums had the same values, so this change is no
functional change.  Thanks for the patch!
