net: bcmgenet: return correct value 'ret' from bcmgenet_power_down

[ Upstream commit 0db55093b56618088b9a1d445eb6e43b311bea33 ]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/net/ethernet/broadcom/genet/bcmgenet.c: In function 'bcmgenet_power_down':
drivers/net/ethernet/broadcom/genet/bcmgenet.c:1136:6: warning:
 variable 'ret' set but not used [-Wunused-but-set-variable]

bcmgenet_power_down should return 'ret' instead of 0.
