[Intel-gfx] [PATCH i-g-t v3] tests/gem_exec_params: check invalid flags for Resource Streamer

[Abdiel Janulgue]

Make sure resource streamer flags works only in correct ring in
addition to checking next flag after the RS boundary fails.

v2: Make sure we reject RS on pre-hsw.
v3: Don't skip 1<<15 for the exec flags (Jani Nikula)
