Because we record connector_mask using 1 << drm_connector_index now the connector_mask should stay the same even when other connectors are removed. This was not the case with MST, in that case when removing a connector all other connectors may change their index.
This is fixed by waiting until the first get_connector_state to allocate connector_state, and force reallocation when state is too small.
As a side effect connector arrays no longer have to be preallocated, and can be allocated on first use which means a less allocations in the page flip only path.
Daniel you said something on irc about v2 of this for -fixes? Did I miss v2?
