[igt-dev] [PATCH i-g-t v2] chamelium: Handle errors when fetching AdapterAllowed

[Petri Latvala <petri.latvala@intel.com>]

Not setting AdapterAllowed in .igtrc should be considered a valid
configuration. The default value of 'false' from
g_key_file_get_boolean when the field is missing is exactly what we
want to use, and storing the missing field error in the 'error'
variable leads to an error such as

(kms_chamelium:1713) igt_chamelium-WARNING: Failed to read chamelium port ID for DP-3: Key file does not have key “AdapterAllowed” in group “Chamelium:HDMI-A-2”

v2: Check if the field exists first to get syntax validation
    happening, handle the error accordingly by bailing out (Ryszard)
