tests/kms_frontbuffer_tracking: Don't unset mode after reading CRC
Until the previous commit we had to disable the mode after reading CRC
because otherwise we might not have been enable features correctly.
Now we can just stage the disable without applying it, so each subtest
can set its desired mode and igt_display will update the state as
required.
Behavior with legacy PSR:
- Modeset enable, read CRC, enable legacy PSR switch, disable CRTC if
using legacy PSR by calling igt_display_commit. Next enable CRTC will
enable PSR.
Behavior with debugfs PSR:
- Modeset enable
- Read CRC
- Enable debugfs PSR switch. PSR enabled.
- Next commit will be done by test, which can disable the mode or set a
mode. The latter case will be a compatible mode, in which case we
avoid the modeset.
