drm/radeon/evergreen_cs: Add missing NULL prefix check in surface check

Browse source

'evergreen_surface_check' is called with a NULL warning prefix when
handling potentially recoverable issues or just to compute the alignment
requirements, and 'evergreen_surface_check' is called again in case of
failure (with the correct prefix, as opposed to NULL), therefore, the
initial check must not print a warning, because the surface may be
accepted successfully after having been corrected, however if it isn't,
the final check will print the warning anyway. The surface check
functions specific to array modes already implement this behavior, but
the 'evergreen_surface_check' function itself doesn't.

This is also supposed to fix the "'%s' directive argument is null
[-Werror=format-overflow=]" compiler warning.
