myri10ge: Fix an error handling path in myri10ge_probe()

[ Upstream commit d83b950d44d2982c0e62e3d81b0f35ab09431008 ]

Some memory allocated in myri10ge_probe_slices() is not released in the
error handling path of myri10ge_probe().

Add the corresponding kfree(), as already done in the remove function.
