ACPI / dock: avoid initializing acpi_dock_notifier_list multiple times
Function dock_add() will be called multiple times if there are
multiple dock stations, which causes acpi_dock_notifier_list to be
initialized multiple times.
To avoid that, move the initialization of acpi_dock_notifier_list
from dock_add() to acpi_dock_init().
