Function dmi_matches can me made a bit faster:
* The documented purpose of dmi_initialized is to catch too early
calls to dmi_check_system(). I'm not fully convinced it justifies
slowing down the initialization of all systems out there, but at
least the check should not have been moved from dmi_check_system()
to dmi_matches(). dmi_matches() is being called for every entry of
the table passed to dmi_check_system(), causing the same redundant
check to be performed again and again. So move it back to
dmi_check_system(), reverting this specific portion of commit
d7b1956fed ("DMI: Introduce dmi_first_match to make the interface
more flexible").
* Don't check for the exact_match flag again when we already know its
value.
