factor: Only check ordering if factor has been setup

2c7c0729 introduced better printing of the ordering type for
PCView_Factor. We must, however, only look for the ordering if the PC
has been setup (otherwise factor->fact is NULL). Fixes #684.

Most external factorization packages do not use the ordering provided by PETSc, therefor only provide it when needed.

Adds MatOrderingType external to indicate not to generate an ordering and use what the package needs
Now -pc_view will not print the wrong PETSc ordering when the ordering is done externally

Saves some memory and compute time.
