Rong ChenandGreg Kroah-Hartman b515552d41 mmc: meson: Fix usage of meson_mmc_post_req() ...

commit f0d2f15362 upstream.

Currently meson_mmc_post_req() is called in meson_mmc_request() right
after meson_mmc_start_cmd(). This could lead to DMA unmapping before the request
is actually finished.

To fix, don't call meson_mmc_post_req() until meson_mmc_request_done().
