[PATCH 1/1] drm/radeon: avoid NULL dereference, si_get_vce_clock_voltage

[Heinrich Schuchardt]

It does not make sense to check if table is NULL
and afterwards to dereference it without
considering the result.

The inconsistency was indicated by cppcheck.
An actual NULL pointer dereference was not observed.
