modpost: refactor seen flag clearing in add_depends()
You do not need to iterate over all modules for resetting ->seen flag because add_depends() is only interested in modules that export symbols referenced from the given 'mod'. This also avoids shadowing the 'modules' parameter of add_depends(). Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
