1. Close connection on ErrPktSync and ErrPktSyncMul …

   An `ErrPktSync` or `ErrPktSyncMul` error always means that a packet
   header has been read, but since the sequence ID was not correct then the
   packet payload has not been read. This results in the connection being
   left in a broken state, since any future operations will always result
   in a "busy buffer" error. Keeping such connections alive leads to them
   being repeatedly returned to the pool in this state, which can in turn
   result in a large number of failures due to these "busy buffer" errors.
   
   This commit fixes this problem by simply closing the connection before
   returning either `ErrPktSync` or `ErrPktSyncMul`. This ensures that the
   connection won't be returned to the pool, preventing it from causing any
   further errors.
