drm/msm/dpu: reorder pointer operations after sanity checks to avoid NULL deref
_dpu_encoder_trigger_start dereferences "struct dpu_encoder_phys *phys"
before the sanity checks which can lead to a NULL pointer dereference if
phys is NULL.
Fix this by reordering the dereference after the sanity checks.
