Description

See http://qpid.2158936.n2.nabble.com/Drain-issue-in-proton-C-td7681843.html

 

When draining a receiver link in the proton c++ api, if there are insuffficient messages on the source, the draining mode gets stuck on so that subsequent granting of credit causes the credit to be immediately drained.

This appears to be due to the flag not being set on the pn_link_t instance.
