[PATCH] io: statx, fstatat: Drop nonnull attribute on the path argument

[Xi Ruoyao <xry111@xry111.site>]

From: Miao Wang <shankerwangmiao@gmail.com>

Since Linux 6.11 the kernel allows path to be NULL if flags &
AT_EMPTY_PATH.  Let's allow users to take the advantage if they don't
care running on old kernels.

[ xry111: separate the obvious change from the controversial
  "io: statx, fstatat64: allow using NULL as path" patch ]
