ASoC: sprd: Fix return value check in sprd_mcdt_probe()
In case of error, the function devm_ioremap_resource() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().
Fixes: d7bff893e04f ("ASoC: sprd: Add Spreadtrum multi-channel data transfer support")
