[igt-dev] [i-g-t] tests/kms_setmode: Handle unsupported modes for invalid crtc test

[Tejas Upadhyay]

Unsupported modes in crtc need to return proper error in order
to report back that applied config was failed or not. Thus added
ENOENT error.

Test affected (fail -> pass after change) :
igt at kms_setmode@invalid-clone-single-[crtc|crtc-stealing]
