test: Fix a maybe-uninitialised compiler warning (#5269)

The compiler warning is a false positive, since n_addresses is always
initialised on the success path from parse_argv(), but the compiler
obviously can’t work that out.

Fixes:
   src/test/test-nss.c:426:9: warning: 'n_addresses' may be used uninitialized in this function [-Wmaybe-uninitialized]
