usb: roles: Fix return value check in intel_xhci_usb_probe()
In case of error, the function devm_ioremap_nocache() returns NULL
pointer not ERR_PTR(). The IS_ERR() test in the return value check
should be replaced with NULL test.
Fixes: f6fb9ec02be1 ("usb: roles: Add Intel xHCI USB role switch driver")
