[Intel-gfx] [PATCH i-g-t] lib: fix igt_reset_connectors

[Thomas Wood]

Use igt_debugfs_open to open the connector file, since the
forced_connectors array now only stores the connector path relative to
the debugfs path. Also add some extra error checking to ensure a test
failure if the reset fails.
