Subject: [PATCH 3/3] scripts/export_report.pl: fix modversion checking

From: Xie XiuQi <xiexiuqi@...wei.com>

The definition of the "__versions" section has changed, so use the
newest format. Otherwise, the list of export-symbol-usage is empty.

  $ make export_report
  ...
  SECTION 2:
          This section reports export-symbol-usage of in-kernel
  modules. Each module lists the modules, and the symbols from that module that
  it uses.  Each listed symbol reports the number of modules using it
  
  NOTE: Got 9 CONFIG_MODVERSIONS warnings

Fixes: a3d0cb04f7df ("modpost: use __section in the output to *.mod.c"),
Fixes: 33def8498fdd ("treewide: Convert macro and uses of __section(foo) to __section("foo")")
