Keep any (near) null space attached to submatrices in PCFIELDSPLIT even if the nonzero structure of the original matrix changes.

Also applied to PCBJACOBI and PCASM

Reported-by: "Jeremy Theler (External)" <jeremy.theler-ext@ansys.com>

The long-term way to handle this is to have MatGetSubMatr*() reuse the same submatrix objects even if the nonzero structure changes. This would just require a bit of recoding in multiple places.
