mmc: uniphier-sd: Fix a resource leak in the remove function
Description

In the Linux kernel, the following vulnerability has been resolved: 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.
