The "cleanup" label in ssl_verify.c:verify_user_pass_plugin() is used
only when PLUGIN_DEF_AUTH is defined, therefore make the label
definition dependent on the same define.

Fixes the following warning when PLUGIN_DEF_AUTH is not defined:

ssl_verify.c: In function 'verify_user_pass_plugin':
ssl_verify.c:1223:1: warning: label 'cleanup' defined but not used [-Wunused-label]
 cleanup:
 ^~~~~~~
