[igt-dev] [PATCH i-g-t] tests/i915_pm_sseu: Don't try to get enabled subslices if it's not there

[Arkadiusz Hiler]

The debugfs contains "Enabled SliceX subslices:" line only if a given
slice is enabled. If we try to dbg_get_status() with everything shut
down we will get a confusing assertion failure:

CRITICAL: Test assertion failure function dbg_get_int, file ../tests/i915/i915_pm_sseu.c:120:
CRITICAL: Failed assertion: pos != NULL

To fix that let's just read the enabled subslices if the line is there,
