gianfar: Fix a locking bug in gianfar's sysfs code
During sparse cleanup, found a locking bug. Some of the sysfs functions were acquiring a lock, and then returning in the event of an error. We rearrange the code so that the lock is released in error conditions, too. Signed-off-by: Andy Fleming <afleming@freescale.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
