Subject: [PATCH 2/8] scripts: get_abi.pl: call get_leave() a little late

The $what conversions need to replace some characters to avoid
breaking regex expressions found on some What:.

only after replacing them back, the script should get the
$leave devnode.

Fixes: ca8e055c2215 ("scripts: get_abi.pl: add a graph to speedup the undefined algorithm")
