Fixed precset to call smoother when it does not know what is asked of
it. 
Taken out krylov subdir, does not make sense anymore.

! Module: psb_prec_mod
!
! This version of the preconditioner module psb_prec_mod renames "on the fly"
! the MLD2P4 preconditioner routines and data types so that the Krylov solvers
! in PSBLAS can be tricked into using the MLD2P4 versions instead of the original
! ones. Since there is no native runtime polymorphism this implies a recompilation,
! but thanks to the renaming feature of Fortran 95 (and to the compatibility of
! the calling sequences) there is no need to change the source code for the
! Krylov methods.
