When mmc allocation succeeds, the error paths are not freeing mmc. Fix the above issue by changing mmc_alloc_host() to devm_mmc_alloc_host() to simplify the error handling. Remove label 'probe_free_host' as devm_* api takes care of freeing, also remove mmc_free_host() from remove function as devm_* takes care of freeing.
