s3:winbindd: Improve performance of lookup_groupmem() in idmap_ad
The LDAP query of lookup_groupmem() returns all group members from AD
even those with missing uidNumber. Such group members are useless in
UNIX environment for idmap_ad backend since there is no uid mapping.
'test_user' is member of group "Domanin Users" with 200K members,
only 20K members have set uidNumber.
Without this fix:
$ time id test_user
real 1m5.946s
user 0m0.019s
sys 0m0.012s
With this fix:
$ time id test_user
real 0m3.544s
user 0m0.004s
sys 0m0.007s
