Subject: [PATCH Bug fix 4/5] Bug fix: Fix section mismatch problem of release_firmware_map_entry().

The function release_firmware_map_entry() references the function
__meminit firmware_map_find_entry_in_list(). So it should also have
__meminit.

And since the firmware_map_entry->kobj is initialized with memmap_ktype,
the memmap_ktype should also be prefixed by __refdata.
