Remove unneeded D_NEEDGIANT from /dev/fd/{0,1,2}.
There is no reason the fdopen() routine needs Giant. It only sets
curthread->td_dupfd, based on the device unit number of the cdev.
I guess we won't get massive performance improvements here, but still, I
assume we eventually want to get rid of Giant.
