staging: fsl-mc: fix asymmetry in destroy of mc_io
An mc_io represents a mapped MC portal. Previously, an mc_io was
created for the root dprc in fsl_mc_bus_probe() and for child dprcs
in dprc_probe(). But the free of that data structure happened in the
general bus remove callback. This asymmetry resulted in some bugs due
to unwanted destroys of mc_io object in some scenarios (e.g. vfio).
Fix this bug by making things symmetric-- mc_io created in
fsl_mc_bus_probe() is freed in fsl_mc_bus_remove(). The mc_io created
in dprc_probe() is freed in dprc_remove().
