Subject: [PATCH] net: fec: fix missing kmalloc() failure check in
 fec_enet_alloc_buffers()

fec_enet_alloc_buffers() assumes that kmalloc() will never fail, which
is an invalid assumption.  Fix this by implementing a common error
cleanup path, and use it to also clean up after failed bounce buffer
allocation.
