[Tarantool-patches] [PATCH] test: unit/popen -- fix potential uninitialized access

[Cyrill Gorcunov]

If handle allocation failed we may access unitialized
variable. Not a big deal in this particular case but
better to be on safe side and make compilers happy.

Otherwise some compiers complain and master branch doesn't pass testing.
