[PATCH] pcnet32: remove incorrect pcnet32_free_ring

Browse Source 
During a code scan for another change I discovered that this call to
pcnet32_free_ring must be removed.  If the open fails due to a lack of
memory all the ring structures are removed via the call to free_ring
and a subsequent call to open will dereference a null pointer in
pcnet32_init_ring.

Please apply to 2.6.17.
