drm/amdgpu: check memory allocation failure

Check memory allocation failure and return -ENOMEM in such a case.

'num_post_dep_syncobjs' still has to be set to 0 before the test in order
to have it initialized if 'amdgpu_cs_parser_fini()' is called to free
resources.

The calling graph would be, in such a case!
   failure in amdgpu_cs_process_syncobj_out_dep()
      ---> error code returned by amdgpu_cs_dependencies()
         --> amdgpu_cs_parser_fini() is called
