[tarantool-patches] [PATCH] Close socket explicitly before wal_dir at exit

[Ilya Kosarev <i.kosarev@tarantool.org>]

tarantool instance didn't close socket explicitly which could cause hot standby instance to fail to bind in case it tries to bind before socket is closed by OS. Now it is fixed by closing socket explicitly before wal_dir.

Closes #3967
