Subject: [PATCH 4/4] modpost: do not set ->preloaded for symbols from Module.symvers

Now that there is no overwrap between symbols from ELF files and
ones from Module.symvers.

So, the 'exported twice' warning should be reported irrespective
of where the symbol in question came from. Only the exceptional case
is when __crc_<sym> symbol appears before __ksymtab_<sym>. This
typically occurs for EXPORT_SYMBOL in .S files.
