X-Git-Tag: v240~486^2~3

reply-password: initialize 'length' variable

Follow-up for 1fd2786161feba4276a81c3468cfbfb118f56517.

This fixes the following warning when built by clang:
```
../src/reply-password/reply-password.c:76:21 warning: variable 'length' is used uninitialized whenever 'if' condition is true [-Wsometimes-uninitialized]
```

Fixes CID#1396281 and CID#1396277.
