Currently the loadble module symbol parsing code is only decoding
the symbol names without prefixing the module names. This will
result in some confusion when two module's symbol names are
identical, and things get worse espeicially when parsing RAM
dumps where two WLAN drivers are loaded.

Prefix module names to module specific symbol names when parsing
their symbol files so user can easily tell which module is
involved in a call stack.
