[igt-dev] [PATCH v2] lib/igt_chamelium: Check for error instead of port id for invalid

[Mark Yacoub <markyacoub@chromium.org>]

[Why]
Chamelium V3 has a valid port 0 so 0 should not be rejected.

[How]
Check if there is an error set from g_key_file_get_integer instead of
depending on port id.

v1:
Use GError instead of check for port ID range.

Test: ./kms_chamelium --run-subtest dp-hp
Tested on: Volteer & cv3
