NFS: alloc_nfs_open_context() must use the file cred when available
If we're creating a nfs_open_context() for a specific file pointer, we must use the cred assigned to that file. Fixes: a52458b48af1 ("NFS/NFSD/SUNRPC: replace generic creds with 'struct cred'.") Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
