[PATCH 6.12.y 3/5] NFSv4/flexfiles: Remove cred local variable dependency

[Sasha Levin <sashal@kernel.org>]

From: Jonathan Curley <jcurley@purestorage.com>

[ Upstream commit fec80afc41afa3016421115427df8d00dc491ee5 ]

No-op preparation change to remove dependency on cred local
variable. Subsequent striping diff has a cred per stripe so this local
variable can't be trusted to be the same.
