platform/mellanox: mlxreg-hotplug: Fix uninitialized variable
With gcc-4.1.2:
drivers/platform/mellanox/mlxreg-hotplug.c: In function ‘mlxreg_hotplug_health_work_helper’:
drivers/platform/mellanox/mlxreg-hotplug.c:347: warning: ‘ret’ is used uninitialized in this function
Indeed, if mlxreg_core_item.count is zero, ret is used uninitialized.
While this is unlikely to happen (it is set to ARRAY_SIZE(...) in x86
board files), this is done in another source file, so fix this by
preinitializing ret to zero.
