Log:
  MFC r305360:
  
  With clang 3.9.0, compiling cxgb results in the following warning:
  
  sys/dev/cxgb/cxgb_sge.c:2873:44: error: implicit conversion from 'int'
  to 'char' changes value from 128 to -128 [-Werror,-Wconstant-conversion]
                          *mtod(m, char *) = CPL_ASYNC_NOTIF;
                                           ~ ^~~~~~~~~~~~~~~
  
  This is because CPL_ASYNC_NOTIF is 0x80, so the plain char argument is
  wrapped to a negative value.  Fix this by using uint8_t instead.
