drm/msm: fix workqueue leak on bind errors
commit
a75b49db6529b2af049eafd938fae888451c3685 upstream.
Make sure to destroy the workqueue also in case of early errors during
bind (e.g. a subcomponent failing to bind).
Since commit
c3b790ea07a1 ("drm: Manage drm_mode_config_init with
drmm_") the mode config will be freed when the drm device is released
also when using the legacy interface, but add an explicit cleanup for
consistency and to facilitate backporting.
Fixes: 060530f1ea67 ("drm/msm: use componentised device support")
