net: fsl-mc: NULL check dflt_dpni before dereference

In dpni_exit there is a NULL check for dflt_dpni after it is
dereferenced a number of times. Instead move the NULL check to early in
the function. Also assign NULL to dflt_dpni after free in both dpni_init
and dpni_exit.

This issue was found by Smatch.
