mtd: rawnand: meson: fix a potential memory leak in meson_nfc_read_buf

meson_nfc_dma_buffer_setup() is called with the "info" buffer which is
allocated a few lines before using kzalloc(). If
meson_nfc_dma_buffer_setup() fails we need to free the allocated "info"
buffer instead of only freeing it upon success.
