BUG/MEDIUM: map: segmentation fault with the stats's socket command "set map ..."

Browse Source 
The value of the variable "appctx->ctx.map.ent" is used after the loop,
but its value has changed. The variable "value" is initialized and
contains the good value.

This is a recent bug, no backport is needed.
