Inserting and ejecting a disc there adds and removes the umd0:/umd1:/
umd:/disc0: mounts, and MetaFileSystem's state pairs sections with mounts
by position without recording which disc was in. A state could then fail
to load, or load one disc's open files onto another. The pause screen
already hid its save buttons for vshmain.prx; the save hotkeys, rewind,
the ImDebugger and the WebSocket debugger all went around that. The check
is now in SaveState itself, and rewind snapshots aren't taken. Verify
still runs, since it reads back with the mounts as they are.
A proper fix records the mounted image in sceUmd's state and remounts it
on load.
