glusterd: try to connect on GF_PMAP_PORT_FOREIGN aswell
This patch fix couple of things mentioned below:
1. previously we use to try to connect on only GF_PMAP_PORT_FREE
in the pmap_registry_alloc(), it could happen that some foreign process
would have freed the port by this time ?, hence it is worth giving a try on
GF_PMAP_PORT_FOREIGN ports as well instead of wasting them all.
2. fix pmap_registry_remove() to mark the port asGF_PMAP_PORT_FREE
3. added useful comments on gf_pmap_port_type enum members
