winbindd: Use talloc_zero_array for consistency with other winbindd_domain
allocators
The other allocator for this structure uses talloc_zero()

winbindd: Do re-connect if the RPC call fails in the passdb case
This is very, very unlikely but possible as in the AD case the RPC server
is in
another process that may eventually be able to restart.

commit d418d0ca33afb41a793a2fff19ca68871aa5e9ef
Author: Andrew Bartlett <abart...@samba.org>

winbindd: Add a cache of the samr and lsa handles for the passdb domain
This domain is very close, in AD DC configurations over a internal ncacn_np
pipe
and otherwise in the same process via C linking. It is however very
expensive
to re-create the binding handle per SID->name lookup, so keep a cache.
