Summary
mmc: wmt-sdmmc: fix return value check of mmc_add_host()
Details

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

mmc: wmt-sdmmc: fix return value check of mmcaddhost()

mmcaddhost() may return error, if we ignore its return value, the memory that allocated in mmcallochost() 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 goto error path which will call mmcfreehost(), besides, clkdisableunprepare() also needs be called.
