drm/vc4: perfmon: Fix variable dereferenced before check
Commit 30f8c74ca9b7 ("drm/vc4: Warn if some v3d code is run on BCM2711")
introduced a check in vc4_perfmon_get() that dereferences a pointer before
we checked whether that pointer is valid or not.
Let's rework that function a bit to do things in the proper order.
