net: ftgmac100: fix ring allocation unwind on open failure

In the Linux kernel, the following vulnerability has been resolved:

net: ftgmac100: fix ring allocation unwind on open failure

ftgmac100_alloc_rings() allocates rx_skbs, tx_skbs, rxdes, txdes, and
rx_scratch in stages. On intermediate failures it returned -ENOMEM
directly, leaking resources allocated earlier in the function.

Rework the failure path to use staged local unwind labels and free
allocated resources in reverse order before returning -ENOMEM. This
matches common netdev allocation cleanup style.
