_ldap_authentication_verify_user_profile() always passes on first page load

Apologies if this is intentional or there is an issue open for this (I did look), but when testing some issues we had with a search crawler user being prompted to update their email.

I noticed that the _ldap_authentication_verify_user_profile() function returns TRUE regardless of whether the regex check failed or not. This however only matters on the first page load as it is saved in $_SESSION and that is what is returned the next time the function runs.

Simple 1 line patch to fix the issue, I'm also having strange regex issues with the matching (hence how I found this issue) and will report that too in a separate issue if it turns out to be a bug.

Patch to follow.
