[PATCH v3 0/1] MR1810: winebus.sys: Fix the build without HAVE_SYS_INOTIFY_H

[Gerald Pfeifer (＠gerald)]

find_device_from_devnode was guarded by HAVE_SYS_INOTIFY_H, alas its
use in process_monitor_event was not, so linking failed.

On the way reduce the scope of a variable (which makes sense per se
and avoids introducing a compiler warning with this change).
