svcrpc: simpler request dropping
Currently we use -EAGAIN returns to determine when to drop a deferred
request. On its own, that is error-prone, as it makes us treat -EAGAIN
returns from other functions specially to prevent inadvertent dropping.
So, use a flag on the request instead.
Returning an error on request deferral is still required, to prevent
further processing, but we no longer need worry that an error return on
its own could result in a drop.
