Masahiro Yamada 1a9031d233 modpost: fix section mismatch check for exported init/exit sections 
BugLink: https://bugs.launchpad.net/bugs/1986995

commit 28438794aba47a27e922857d27b31b74e8559143 upstream.

Since commit f02e8a6596 ("module: Sort exported symbols"),
EXPORT_SYMBOL* is placed in the individual section ___ksymtab(_gpl)+<sym>
(3 leading underscores instead of 2).

Since then, modpost cannot detect the bad combination of EXPORT_SYMBOL
and __init/__exit.

Fix the .fromsec field.
