Subject: [PATCH 2/2] mmc: uniphier-sd: Fix a resource leak in the remove function

A 'tmio_mmc_host_free()' call is missing in the remove function, in order
to balance a 'tmio_mmc_host_alloc()' call in the probe.
This is done in the error handling path of the probe, but not in the remove
function.

Add the missing call.

Fixes: 3fd784f745dd ("mmc: uniphier-sd: add UniPhier SD/eMMC controller driver")
