renderer/native: Clear old pending mode sets when unsetting all modes

Browse Source 
If we queued a mode set, but didn't end up compositing all frames, we'll
have pending mode sets in a hash table waiting to be applied. If we
before all monitors again try to reconfigure things we should drop the
old pending mode sets and start fresh.

We already do this when we're doing so when generating views, but when
just unsetting modes, we didn't, so fix that.
