Ming Lei 8284066946 ublk: grab request reference when the request is handled by userspace 
Add one reference counter into request pdu data, and hold this reference
in the request's lifetime.

Prepare for supporting to move request data copy into userspace, which
needs to copy request data by read()/write() on /dev/ublkcN, so we have
to guarantee that read()/write() is done on one valid/active request,
and that will be enhanced by holding the io request reference in
read()/write().
