Keep smooth_num_levels in sync with amg_data (#954)

Browse Source 
This solves an out-of-bounds memory error during `hypre_BoomerAMGSetup` when called multiple times without a call to `hypre_BoomerAMGDestroy` interleaved. This pull request makes sure that `smooth_num_levels` is reset to `hypre_ParAMGDataSmoothNumLevels(amg_data)` before the smoothers variable is allocated.
