Bring back O_NDELAY for floppy

Only one commit this time with revert of O_NDELAY removal for the floppy.
Users reported that the commit breaks userspace utils and known floppy
workflow patterns. We already reverted the same commit back in 2016
presumably for the same reason. Completely drop O_NDELAY for floppy seems
excessive to solve problems it introduces.

I started to write basic selftests for the floppy to prevent this kind of
userspace breaks in the future.
