[PATCH v7 03/16] platform/x86: lenovo-wmi-other: Balance component bind and unbind

["Derek J. Clark" <derekjohn.clark@gmail.com>]

From: Rong Zhang <i@rong.moe>

When lwmi_om_master_bind() fails, the master device's components are
left bound, with the aggregate device destroyed due to the failure
(found by sashiko.dev [1]).

Balance calls to component_bind_all() and component_unbind_all() when an
error is propagated to the component framework.

No functional change intended.
