init_common_resources always return 0 and it is redundant to check the
return value, let's make it void to simplify the code.

Although I agree this looks pretty superfluous at the moment, I'd rather
keep init_common_resources as it is at the moment, as we may well end-up
with more stuff in it, which could fail.
Another possibility would be to merge everything in init_subsystems, but
that'd require careful investigation, specially with the stuff that is
currently pending for 4.20.
Thanks,
M.
