Below is a patch to suppress printing uninformative errors from
ide-floppy.c in response to commands to floppy drives in which no media is
present.

Without this patch, commands sent to ide-floppy devices without media
inserted cause error messages on the console (KERN_ERR level) such as:

ide-floppy: ide: I/O error, pc = 0 key = 2, asc = 3a asq = 0
ide-floppy: ide: I/O error, pc = 1b key = 2, asc = 3a asq = 0
ide-floppy: ide: I/O error, pc = 23 key = 2, asc = 3a asq = 0
ide-floppy: ide: I/O error, pc = 1e key = 2, asc = 3a asq = 0
ide-floppy: ide: I/O error, pc = 1e key = 2, asc = 3a asq = 0

Dell's Virtual Floppy (system management presents to the local system an
IDE floppy device, which is actually a floppy device in a remote system
connected over an IP link) exhibits this also, when connecting to a remote
floppy drive with no media present.
