When there are no free snums, UCC ethernet should gracefully fail, but
currently it oopses this way:

 ...

Also, when device tree specifies fixed-link, and CONFIG_FIXED_PHY
is disabled, we'll get this oops:

 ...

This patch fixes all three oopses simply by rearranging some code:

- In ucc_geth_open(): move init_phy() call to the beginning, so
  that we only call ucc_geth_stop() with a PHY attached;
- Move phy_disconnect() call from ucc_geth_close() to
  ucc_geth_stop(), so that we'll always disconnect the PHY.
