[Intel-gfx] [PATCH i-g-t v2 4/5] lib/igt_core.c - Introduce igt_exit_early()

[Dale B Stimson]

Call igt_exit() after dealing with assumptions not valid for early calls.

In particular:

igt_exit() assumes that subtests have been considered for execution.
With --run-subtest, for an early exit (where subtests had not yet been
considered):
- igt_exit() would complain about "Unknown subtest"
- igt_exit() would exit prematurely.
