BUG/MEDIUM: peers: re-work connection to new process during reload.

The peers task handling the "stopping" could wake up multiple
times in stopping state with WOKEN_SIGNAL: the connection to the
local peer initiated on the first processing was immediatly
shutdown by the next processing of the task and the old process
exits considering it is unable to connect. It results on
empty stick-tables after a reload.

This patch checks the flag 'PEERS_F_DONOTSTOP' to know if the
signal is considered and if remote peers connections shutdown
is already done or if a connection to the local peer must be
established.

This patch should be backported on all supported branches (v >= 1.6)
