modpost: fix section mismatch check for exported init/exit sections 



commit 28438794aba47a27e922857d27b31b74e8559143 upstream.

Since commit f02e8a65 ("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.
