Denis Efremov c7e9d00203 Revert "floppy: reintroduce O_NDELAY fix" ...

The patch breaks userspace implementations (e.g. fdutils) and introduces
regressions in behaviour. Previously, it was possible to O_NDELAY open a
floppy device with no media inserted or with write protected media without
an error. Some userspace tools use this particular behavior for probing.

It's not the first time when we revert this patch. Previous revert is in
commit f2791e7ead (Revert "floppy: refactor open() flags handling").

This reverts commit 8a0c014cd2.
