[PATCH] net: mscc: ocelot: Fix a resource leak in the error handling path of the probe function

[Christophe JAILLET]

In case of error after calling 'ocelot_init()', it must be undone by a
corresponding 'ocelot_deinit()' call, as already done in the remove
function.

Fixes: a556c76adc05 ("net: mscc: Add initial Ocelot switch support")
