USB: io_edgeport: fix port-data memory leak

commit c27f3efc56080a246f6ab7f57f0a6f56d256d769 upstream.

Fix port-data memory leak by moving port data allocation and
deallocation to port_probe and port_remove.

Since commit 0998d0631001288 (device-core: Ensure drvdata = NULL when no
driver is bound) the port private data is no longer freed at release as
it is no longer accessible.

Compile-only tested.
