mmc: meson-mx-sdio: check devm_kasprintf for failure

Browse source

[ Upstream commit b0d06f1cb0 ]

devm_kasprintf() may return NULL on failure of internal allocation thus
the assignments to  init.name  are not safe if not checked. On error
meson_mx_mmc_register_clks() returns negative values so -ENOMEM in the
(unlikely) failure case of devm_kasprintf() should be fine here.
