Move the LUSTRE_VERSION_CODE checks to trigger on x.y.53 instead of
x.y.50, so that it is into the development cycle that they are hit
instead of right at the start.
In many cases, the #warning has been removed (to prevent build errors)
and instead the code is just disabled outright. The dead code can be
seen easily and removed in the future with less interruption to the
development process.

Umount process relies on lu_site_purge(-1) to purge all
objects before umount, however, if there happen to have a
cache shrinker which calls lu_site_purge(nr) in parallel,
some objects may still being freed by cache shrinker even
after the lu_site_purge(-1) called by umount done.
This can be simply fixed by serializing purge threads,
since it doesn't make any sense to have them in parallel.
