net: bcmgenet: prevent duplicate calls of bcmgenet_dma_teardown
When bcmgenet_dma_teardown is called from bcmgenet_fini_dma it ends
up getting called twice from the bcmgenet_close and bcmgenet_suspend
functions (once directly and once inside the bcmgenet_fini_dma call).
This commit removes the call from bcmgenet_fini_dma and ensures that
bcmgenet_dma_teardown is called before bcmgenet_fini_dma in all paths
of execution.
Fixes: 4a0c081eff43 ("net: bcmgenet: call bcmgenet_dma_teardown in bcmgenet_fini_dma")
