[Intel-gfx] [PATCH igt] igt/kms_frontbuffer_tracking: Make assert(false) more informative

[Chris Wilson]

When reading CI failure reports seeing an "assertion false failed" is
confusing as you then have to look for the preceding explanation. Show
the actual condition that fails in the assert report. Note that this
give the system a chance at a reprieve and avoids conflicting
information such as:

(kms_frontbuffer_tracking:1649) DEBUG: Test requirement passed: !fbc_not_enough_stolen()
(kms_frontbuffer_tracking:1649) DEBUG: Test requirement passed: !fbc_stride_not_supported()
(kms_frontbuffer_tracking:1649) INFO: FBC status:
FBC disabled: FBC enabled (active or scheduled)

(kms_frontbuffer_tracking:1649) CRITICAL: Test assertion failure function do_status_assertions, file kms_frontbuffer_tracking.c:1714:
(kms_frontbuffer_tracking:1649) CRITICAL: Failed asserti

Where the fbc status tells us that it was indeed enabled, but the assertion still failed.
