[PATCH] USB: ub 03 drop stall clearing

Matt mentioned that a very old ZIP-100 actually does need this, but I am
yet to see anyone who actually has one still working and uses ub with it.
He/she must be a retrocomputing geek, who can easily bias it to usb-storage
with libusual, if needed. Meanwhile, common folks have trouble with poorly
designed USB keys and some el-cheapo European music players. I think we
better drop this for now.
