NFS: Clear NFS_INO_REVAL_PAGECACHE when we update the file size

In nfs_update_inode(), if the change attribute is seen to change on the server, then we set NFS_INO_REVAL_PAGECACHE in order to make sure that we check the file size. However, if we also update the file size in the same function, we don't need to check it again. So make sure that we clear the NFS_INO_REVAL_PAGECACHE that was set earlier.
