Fix null dereference in call_allocate
In call_allocate we need to reach the auth in order to factor au_cslack
into the allocation.
As of a17c2153d2e271b0cbacae9bed83b0eaa41db7e1 "SUNRPC: Move the bound
cred to struct rpc_rqst", call_allocate attempts to do this by
dereferencing tk_client->cl_auth, however this is not guaranteed to be
defined--cl_auth can be zero in the case of gss context destruction (see
rpc_free_auth).
Reorder the client state machine to bind credentials before allocating,
so that we can instead reach the auth through the cred.
