        src/sys/arch/sun3/dev: fd.c

Log Message:
Sync with sparc/dev/fd.c rev 1.155.

> Fix panic() on opening fd(4), caused by a wrong pointer passed to memset().

Note sun3 still uses gcc 4.5.4 but also panicked by this old bug,
so probably this problem was triggered by not gcc 4.8 but struct disk
changes (struct disk_geom was added in <sys/disk.h> rev 1.58),
which increased sizeof(struct fd_softc) from 248 bytes to 296 bytes.
(i.e. now struct fd_softc could be allocated in a different pool block,
 probably near the wrong pointer of the struct disklabel)

Anyway, this fix should be pullued up to netbsd-7.
(probably I'm the only user of floppy on sun3 though)
