David van Moolenbroek 29e004d23b VFS: make message pointer management more robust 
The previous approach of storing pointers to messages structures for
thread-blocking sendrec operations relied on several assumptions,
which if violated could lead to odd cases of memory corruption.
With this patch, VFS resets pointers right after use, avoiding that
any dangling pointers are accidentally dereferenced later.  This
approach was already used in some cases, but not all of them.
