fdread cannot work without opening the /dev/fd node in O_RDWR mode now,

because it sets the floppy controller parameters, which requires O_RDWR.
Specifically, the FD_SOPTS ioctl requires this, and the code errors out
and aborts if it can't do it.  Among other things, it is changing the
FDOPT_NOERRLOG flag.  Broken in 6.0 as well.
