nfs: Fix use of uninitialized variable in nfs_getattr()

commit 16caf5b6101d03335b386e77e9e14136f989be87 upstream.

Variable 'err' needn't be initialized when nfs_getattr() uses it to
check whether it should call generic_fillattr() or not. That can result
in spurious error returns. Initialize 'err' properly.
