Description of problem:
A call to check_account_lock() (providing a slapi_entry) goes on to check
password expiry etc. with a call to new_passwdPolicy() passing in the DN of the
entry. new_passwdPolicy() then searches the db for the entry (that we already
have). This occurs in the bind code path so any optimization here would be good.
 There should be a way to pass in the entry to avoid the search.

new_passwdPolicy() seems to get called a lot in the password management code,
and there look to be other places that might be able to optimize out the search.

new_passwdPolicy() also has this comment
/*  If we're doing an add, COS does not apply yet so we check
                        parents for the pwdpolicysubentry.  We look only for virtual
                        attributes, because real ones are for single-target
policy. */

I'm not sure why this would be true - if an entry could be passed in in from the
add code this shouldn't be an issue I think, and the whole policy searching
algorithm could be ripped out and rely on COS for adds too (might be an issue
with regards to whether the add op has succeeded yet or something).
