Guard PHYSFS_deinit() with PHYSFS_isInit()

Browse source 
A quick glance at PhysFS source code will show that PhysFS will bail if
PHYSFS_deinit() is called if it's not initialized.

"Bail" here just means setting an error code and returning early, so
it's not that bad. Still, it's the principle of the thing, and I just
want to ensure that FILESYSTEM_deinit() can be safely called no matter
if the filesystem hasn't initialized yet; having an error set by PhysFS
kind of taints the whole safety thing, even if it does nothing wrong,
no?

(although, speaking of which, we should be handling all errors by
PhysFS, but that's for later...)
