[ Upstream commit a10a9233073d984b239e22358ba21825e27e2e88 ]
The subjective cred (task->cred) can potentially be overridden and
subsquently freed in non-RCU context, which could lead to a panic if we
try to use it in cred_fscmp(). Use __task_cred(), which returns the
objective cred (task->real_cred) instead.
Fixes: 0eb43812c027 ("NFS: Clear the file access cache upon login")
Fixes: 5e9a7b9c2ea1 ("NFS: Fix up a sparse warning")
