compal-laptop/fujitsu-laptop/msi-laptop: make dmi_check_cb to return 1 instead of 0

dmi_check_system() walks the table running matching functions until
someone returns non zero or we hit the end.

This patch makes dmi_check_cb to return 1 so dmi_check_system() return
immediately when a match is found.
