platform/surface: platform_profile: Propagate error if profile registration fails

Browse source 
commit fe0e04cf66a12ffe6d1b43725ddaabd5599d024f upstream.

If platform_profile_register() fails, the driver does not propagate
the error, but instead probes successfully. This means when the driver
unbinds, the a warning might be issued by platform_profile_remove().

Fix this by propagating the error back to the caller of
surface_platform_profile_probe().

Compile-tested only.
