Yang Yingliang f670744a31 mmc: toshsd: 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 goto error path which will call
mmc_free_host(), besides, free_irq() also needs be called.

Fixes: a5eb8bbd66 ("mmc: add Toshiba PCI SD controller driver")
