spi: ep93xx: fix double-free of zeropage on DMA setup failure
If DMA setup fails after allocating the zeropage, the error path frees
the page but leaves espi->zeropage dangling. A subsequent call to
ep93xx_spi_release_dma() sees the non-NULL pointer and frees the page
again.
Clear the pointer after freeing in the error path of
ep93xx_spi_setup_dma().
