[igt-dev] [PATCH i-g-t 1/2] lib: Skip tests that require fb modifiers when KMS is disabled

[José Roberto de Souza]

When KMS is disabled, drmGetCap() for DRM_CAP_ADDFB2_MODIFIERS() will
return -1 and set errno as EOPNOTSUPP, the current assert was only
checking for a sucess result or invalid argument causing
prime_vgem at basic-fence-flip test to fail when KMS is disabled.
