freedreno/a5xx: fix crash in dEQP-GLES31.stress.vertex_attribute_binding.buffer_bound...

This is kind of a hack, but really the only problem is the
debug_assert() in OUT_RELOC().  But the debug_assert() is
useful to catch real issues.  So just add some #ifdef DEBUG
code to filter things out before we hit the assert.
