mmc: core: fix return value check in devm_mmc_alloc_host()

mmc_alloc_host() returns NULL pointer not PTR_ERR(), if it
fails, so replace the IS_ERR() check with NULL pointer check.

In commit 418f7c2de133 ("mmc: meson-gx: use devm_mmc_alloc_host"),
it checks NULL pointer not PTR_ERR, if devm_mmc_alloc_host() fails,
so make it to return NULL pointer to keep same with mmc_alloc_host(),
the drivers don't need to change the error handle when switch to
use devm_mmc_alloc_host().
