[igt-dev] [PATCH i-g-t 2/2] tests/kms_addfb_basic: Relax errno assertions

[Jeremy Cline]

This adjusts the check on failed calls to DRM_IOCTL_MODE_ADDFB2 in
various scenarios. According to the kernel's
drm_mode_config_funcs.fb_create documentation, a negative return code is
all that is required to signal failure, and different drivers return
different errors in these scenarios.

Particularly, Nouveau returns -ERANGE rather than -EINVAL in scenarios
where the buffer is too small for the proposed configuration.
