[PATCH v2 08/13] selftests: net: netlink-dumps: Avoid uninitialized variable warning

[Guenter Roeck <linux@roeck-us.net>]

The following warning is seen when building netlink-dumps.

netlink-dumps.c: In function ‘dump_extack’:
../kselftest_harness.h:788:35: warning: ‘ret’ may be used uninitialized

Problem is that the loop which initializes 'ret' may exit early without
initializing the variable if recv() returns an error. Always initialize
'ret' to solve the problem.
