i965: Take responsibility for context recovery after any GPU hang

To make wedging even more likely, we use a new "no recovery" context
parameter that tells the kernel to not even attempt to replay any
batches in flight against the default context image, as experience shows
the HW is not always robust enough to cope with the conflicting state.
This allows us to always take over responsibility of rebuilding the lost
context following a GPU hang.
