Got multi-GPU version of createCloverQuda working, but only with Guochun's
extended gauge field routines. createCloverQuda is used to construct the
clover field in loadCloverQuda whenever h_clovinv is not specified.
Need to change the code to call createCloverQuda even when h_clovinv is specified.
Modified loadCloverQuda to call createCloverQuda when h_clover == h_cloverinv == 0
and clover_coeff != 0
