param: Fix duplicate module prefixes
Instead of insisting each new module_param sysfs entry is unique,
handle the case where it already exists (for builtin modules).
The current code assumes that all identical prefixes are together in
the section: true for normal uses, but not necessarily so if someone
overrides MODULE_PARAM_PREFIX. More importantly, it's not true with
the new "core_param()" code which uses "kernel" as a prefix.
This simplifies the caller for the builtin case, at a slight loss of
efficiency (we do the lookup every time to see if the directory
exists).
