[igt-dev] [PATCH v3 i-g-t 02/15] lib/hang: Fix igt_require_hang_ring to work with all engines

[John.C.Harrison at Intel.com]

From: John Harrison <John.C.Harrison at Intel.com>

The above function was checking for valid rings via the old interface.
The new scheme is to check for engines on contexts as there are now
more engines than could be supported.
