[PATCH 5/7] block/nfs: Fix 32-bit Windows build

[Bin Meng]

From: Bin Meng <bin.meng@windriver.com>

libnfs.h declares nfs_fstat() as the following for win32:

  int nfs_fstat(struct nfs_context *nfs, struct nfsfh *nfsfh,
                struct __stat64 *st);

The 'st' parameter should be of type 'struct __stat64'. The
codes happen to build successfully for 64-bit Windows, but it
does not build for 32-bit Windows.

Fixes: 6542aa9c75bc ("block: add native support for NFS")
Fixes: 18a8056e0bc7 ("block/nfs: cache allocated filesize for read-only files")
