drm/i915: Avoid drm_atomic_state_put(NULL) on error paths
The error paths in hsw_trans_edp_pipe_A_crc_wa() and
intel_prepare_reset() would potentially call drm_atomic_state_put with a
NULL state, which would lead to a NULL pointer dereference.
Found by coverity.
v2: Improve the error paths. (Chris)
