libglusterfs : Fix crash in glusterd while peer probing
glusterd crashes when port is being set explcitly to a
range which is outside greater than short data type range.
Eg. sysctl net.ipv4.ip_local_reserved_ports="49152-49156"
In above case glusterd crashes while parsing the port.
With this fix glusterd will be able to handle port range
between INT_MIN to INT_MAX
