Replaced error gotos with direct returns in fsl_mc_allocator_probe()
and fsl_mc_allocator_remove(), since the only error handling done
in those functions is to exit.

Each fsl_mc_io object is associated with an fsl_mc_device object
of type "dpmcp" representing the MC portal associated with the
fsl_mc_io object. Before, we were representing this association with
an fsl_mc_resource pointer. To enhance code clarity, it is more
straight forward to use an fsl_mc_devi
owner needs to be initialized as THIS_MOUDLE.
