Introduce a global mutex and lock it on every callback from VFS.
Performance doesn't matter, reviewing the whole code for locking correctness
would be too complicated, so simply lock it all.

This is the least-bad behaviour. It means that we signal the
vblank event before it actually happens, but since we're disabling
vblanks there's no guarantee that it will *ever* happen otherwise.
This prevents GL applications which use WaitMSC from hanging
indefinitely.

In particular, s_freeing_list needs to be initialized early, since it is
used on some of the error paths when mounts fail. The mapping inode,
for example, would be initialized and then free'd on an error path
before s_freeing_list was initialized, but the inode drop operation
needs the s_freeing_list to be set up.
Normally you'd never see this, because not only is logfs fairly rare,
but a successful mount will never have any issues.
