If scope != LDAP_SCOPE_BASE and a timelimit or sizelimit is exceeded,
rc is returned uninitialized and something (gs.err?) should be set to
LDAP_<TIME/SIZE>LIMIT_EXCEEDED.  Or maybe it should only be set to
*LIMIT_EXCEEDED if there is not a "stronger" error there already.
Though it only pays attention to the _last_ result code in any case;
that seems strange.

Also, rc is returned uninitialized if scope != LDAP_SCOPE_BASE and
there is no backend with a be->be_search routine.

BTW, after fixing this, you'll get rid of a gcc 'variable might
be used uninitialized' warning if you replace the switch with an
`if (scope == LDAP_SCOPE_BASE) ... else ...' statement.
