reestablishing gss context on rpc_reconnect

Browse source 
if we receive an rpc_autherr, just recreate a new rpc client as well
as the rpc auth structure. as it ties into the recovery and handles
that only one thread recovers and reestablishes the rpc auth context.

in theory, reestablishing rpc client does not necessitate new rpc auth
context. we really need to restablish one only if we get rpc autherr. however,
it simplifies the code not to introduce a different synchronization
mechanism for rpc auth in addition to the rpc one.
