[PATCH 2/3] drm/imagination: Detach pm domains if linking fails

[Matt Coster]

There's a missing call to dev_pm_domain_detach_list() in the error path of
pvr_power_domains_init(); if creating the second stage of device links
fails then the struct dev_pm_domain_list will be left dangling.

Fixes: e19cc5ab347e3 ("drm/imagination: Use dev_pm_domain_attach_list()")
