spi: mtk-snfi: Fix resource leak in mtk_snand_read_page_cache()

[ Upstream commit 496ba79b9496b8b3747cbc764ebd33ee7325e806 ]

When DMA read times out in mtk_snand_read_page_cache(), the original code
erroneously jumped to cleanup label which skips DMA unmapping and ECC
disable, causing a resource leak.
