[BUG] Infinite loop when selecting invalid disc

[arp242]

If you select an invalid ROM from "file" -> "Open ROM" (I thought you had to select the BIOS there 😅) CDIDisc::LoadFileSystem() gets stuck in an infinite loop in the while((Tell() % 2352) < 2072) loop. Tell() returns -1, which presumably indicates some failure, but it never checks for this.

I never really did any C++, so no patch, but should be an easy fix.

Also happens if you load the .cue file instead of the .bin file btw.

This is old code that isn't error-proof, it will be in the future

I don't support .cue files, I should remove it from the dialog window until I support them.
