[PATCH RESEND] drm/amd/display: Add otg_master NULL check within init_pipe_slice_table_from_context

[Ma Ke]

To avoid reports of NULL_RETURN warning, we should add
otg_master NULL check.

Fixes: c51d87202d1f ("drm/amd/display: do not attempt ODM power optimization if 
minimal transition doesn't exist")
