qcacmn: Add Sanity Checks
Stats are updated periodically and
are categorized to soc, pdev, and
vdev
While the stats are getting updated
and if pdev, or vdev gets detached
in the same time, the stats handlers
will deference a NULL pointer
Hence Add basic sanity checks to DP
layer for soc, pdev and vdev inside
stat handlers
