igt/kms_fbcon_fbt: Handle ENODEV when checking i915_edp_psr_status for chipset support
If the machine doesn't support PSR, it will return -ENODEV from
i915_edp_psr_status, which we want to interpret as unsupported.
This is in line with what Chris just fixed for FBC.
V2: Copy-pasted to the correct position.
