IB/hfi1: Clean up on context initialization failure
The error path for context initialization is not consistent. Cleanup all
resources on failure.
Removed unused variable user_event_mask.
Add the _BASE_FAILED bit to the event flags so that a base context can
notify waiting sub contexts that they cannot continue.
Running out of sub contexts is an EBUSY result, not EINVAL.
