[FLOPPY] Don't wait forever while trying to determine media type.

Browse source 
This should fix some virtual machines and real hardware machine with empty floopy drive
not being able to boot ReactOS (stuck while initializing floppy.sys).
This fixes a regression introduced in r70746.
It could be generalized to other interrupts, floppy controllers not being reliable.
