driver core: Annotate dev_err_probe() with __must_check 



commit e1f82a0dcf388d98bcc7ad195c03bd812405e6b2 upstream.

We have got already new users of this API which interpret it differently
and miss the opportunity to optimize their code.

In order to avoid similar cases in the future, annotate dev_err_probe()
with __must_check.
