drm: of: drm_of_find_panel_or_bridge: simplify error return paths

In prepataion to further modify the logic of this function, simplify the
error-returning code.

With this change, on any error there is an immediate 'return -<ERRNO>;'
statement, without having to carry on the return value until the end.

Additionally, clear both the panel and the bridge pointers at the
beginning. Even though this is redundant in some code paths, it allows to
have a simpler code in the rest of the function.
