[igt-dev] [PATCH i-g-t 3/3] tests/i915/gem_exec_schedule: Use separate context for spinner

["Zbigniew Kempczyński" <zbigniew.kempczynski@intel.com>]

Iterating over all physical engines on default context is wrong and
it may end with failure when there're more engines than default context
contains. To handle this we should create separate context on top of
all-physical-engines config.
