A field in an osd request keeps track of whether a connection is
currently filling the request's reply message. This patch gets rid
of that field.
An osd request includes two messages--a request and a reply--and
they're both associated with the connection that existed to its
the target osd at the time the request was created.
An osd request can be dropped early, even when it's in flight.
And at that time both messages are released. It's possible the
reply message has been supplied to its connection to receive
an incoming response message at the time the osd request gets
dropped. So ceph_osdc_release_request() revokes that message
from the connection before releasing it so things get cleaned up
properly.
Previously this may have caused a problem, because the connection
that a message was associated with might have gone away before the
revoke request. And to avoid any problems using that connection,
the osd client held a reference to it when it supplies its response
message.
