drm/amd/display: Handle dml allocation failure to avoid crash

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Handle dml allocation failure to avoid crash

[Why]
In the case where a dml allocation fails for any reason, the
current state's dml contexts would no longer be valid. Then
subsequent calls dc_state_copy_internal would shallow copy
invalid memory and if the new state was released, a double
free would occur.

[How]
Reset dml pointers in new_state to NULL and avoid invalid
pointer
