Patch file for thread.c of version 2.9.2

Race condition in threads.c specific for the win32 platform.

The reference count is decremented outside of the critical section. 
A race condition can cause the lock not to be released.

Fix race condition

There is no need for 'count' at all. CRITICAL_SECTION is already reentrant-save.

The issue is critical because application could hang when running two xmlReadMemory simultaneously on multiprocessor system.
Comment 2 GNOME Infrastructure Team 2021-07-05 13:25:42 UTC 
GNOME is going to shut down bugzilla.gnome.org in favor of gitlab.gnome.org.
As part of that, we are mass-closing older open tickets in bugzilla.gnome.org
which have not seen updates for a longer time (resources are unfortunately
quite limited so not every ticket can get handled).

If you can still reproduce the situation described in this ticket in a recent
and supported software version, then please follow
  https://wiki.gnome.org/GettingInTouch/BugReportingGuidelines
and create a new ticket at
  https://gitlab.gnome.org/GNOME/libxml2/-/issues/

Thank you for your understanding and your help.
