Bug #1245: Errors when writing to memory stick with dd

When I was trying to create a DragonFly Live-USBstick using
dd if=/usr/release/dfly.img of=/dev/da0 bs=1m
It kept on failing with errors several times but got "unstuck" when I
pulled out the USB stick. Finally dd worked, but only after 5 tries.

Errors were of the following sort with many repeated messages:

umass0: <USB DISK 2.0, class 0/0, rev 2.00/4.11, addr 2> on uhub0

and more and more... until it just worked!
