usb: chipidea: msm: Fix return value check in ci_hdrc_msm_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: 2fc305be364e ("usb: chipidea: msm: Mux over secondary phy at the
right time")
