BUG/MINOR: quic: reappend rxbuf buffer on fake dgram alloc error

A thread must always reappend the rxbuf instance after finishing
datagram reception treatment. This was not the case on one error code
path : when fake datagram allocation fails on datagram requeing.

This issue was introduced with the following patch :
  commit b34d353968db7f646e83871cb6b21a246af84ddc
  BUG/MEDIUM: quic: consume contig space on requeue datagram
As such, it must be backported in every version with the above commit.
