[PATCH 1/7] fs: exfat: Flush node before put in read() callback

[Marek Vasut <marex@denx.de>]

Make sure the node is never dirty before being released, flush
the node first using exfat_flush_node() and only then release
the node using exfat_put_node(). This now matches the behavior
of exfat_fs_write() too.
