[PATCH for-next 6/6] IB/core: Rename uverbs event file structure

[Matan Barak <matanb-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>]

Previously, ib_uverbs_event_file was suffixed by _file as it contained
the actual file information. Since it's now only used as base struct
for ib_uverbs_async_event_file and ib_uverbs_completion_event_file,
we change its name to ib_uverbs_event_queue. This represents its
logical role better.

Fixes: 1e7710f3f656 ('IB/core: Change completion channel to use the reworked objects schema')
