msm: camera: isp: Don't move substate to SOF

In RDI only usecase, if we get RUP and buf done
late, then we will enter bubble substate. In
current logic, we will move to SOF substate if
we get SOF in bubble substate, it causes the
buf done of bubble req can't be received. Since
we don't have valid interface for buf done in
SOF substate.
This changes don't move substate to SOF if we
are processing bubble.
