Wei Chen dce6d8f985 mmc: sunplus: fix return value check of mmc_add_host() 
mmc_add_host() may return error, if we ignore its return value,
1. the memory allocated in mmc_alloc_host() will be leaked
2. null-ptr-deref will happen when calling mmc_remove_host()
in remove function spmmc_drv_remove() because deleting not
added device.

Fix this by checking the return value of mmc_add_host(). Moreover,
I fixed the error handling path of spmmc_drv_probe() to clean up.

Fixes: 4e268fed8b ("mmc: Add mmc driver for Sunplus SP7021")
