Original isp116x-hcd code prepared multiple PTDs for longer than 16
byte transfers for one endpoint. That is unnecessary because the
ISP116x is able to split long data from one PTD into multiple
transactions based on the buffer size of the endpoint. It also caused
serious problems if the endpoint NAKed some of the transactions. In
that case ISP116x wouldn't notice that the other PTDs were for the same
endpoint and would try the other PTDs possibly out of order. That would
break the whole transfer.
This patch makes isp116x_submit_job to use one PTD for one transfer.

Using some (very) slow USB keys cause the USB host controller buffers
are not ready to be read by the CPU so we need an extra delay before
reading the USB storage data.
