ufshci: tell the controller how long the EHS is

The transfer request descriptor has a field for the total Extra Header
Segment length. The driver left it at zero. A request that carried an
EHS went out as the bare command UPIU, and the device answered a request
it had only seen part of.

Fill the field from the request UPIU header, which already carries the
same length. Every other path sets it to zero, so nothing else changes.
An EHS is the first thing that makes a request vary in size, so assert
that the request and the response still fit in the command descriptor.
