qcacmn: Add the api to set smmu fault state

There is a time involved between the smmu fault initiated
and the eventual system panic. In this time there is a
possibility of the nbuf history being overwritten losing
the information on the nbuf which might has actually caused
the SMMU fault.

Set the ssmu state and dont track the nbuf's when the smmu
fault is detected.
