NFSv4: Clear the NFS_CAP_XATTR flag if not supported by the server

[ Upstream commit 4fb2b677fc1f70ee642c0beecc3cabf226ef5707 ]

nfs_server_set_fsinfo() shouldn't assume that NFS_CAP_XATTR is unset
on entry to the function.

Fixes: b78ef845c35d ("NFSv4.2: query the server for extended attribute support")
