Xu Yang f96c038404 usb: chipidea: core: fix possible constant 0 if use IS_ERR(ci->role_switch) 
After successfully probed, ci->role_switch would only be NULL or a valid
pointer. IS_ERR(ci->role_switch) will always return 0. So no need to wrap
it with IS_ERR, otherwise the logic is wrong.

Fixes: e1b5d2bed6 ("usb: chipidea: core: handle usb role switch in a common way")
