[igt-dev] [RFC PATCH v7 4/5] lib: ioctl_wrappers: reach engines by index as well

[Andi Shyti]

With the new engine query method engines are reachable through
an index and context they are combined with.

The 'gem_has_ring()' becomes 'gem_has_ring_by_idx()' that
requires the index that the engine is mapped with in the driver.

The previous function becomes a wrapper to the new
'gem_has_ring_by_idx()'.
