CVE-2022-50347

mmc: rtsx_usb_sdmmc: fix return value check of mmc_add_host()

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

mmc: rtsx_usb_sdmmc: fix return value check of mmc_add_host()

mmc_add_host() may return error, if we ignore its return value, the memory
that allocated in mmc_alloc_host() will be leaked and it will lead a kernel
crash because of deleting not added device in the remove path.

So fix this by checking the return value and calling mmc_free_host() in the
error path, besides, led_classdev_unregister() and pm_runtime_disable() also
need be called.
