mfd: twl-core: Return directly after a failed platform_device_alloc() in add_numbered_child()
The platform_device_put() function was called in one case by the
add_numbered_child() function during error handling even if the passed
variable "pdev" contained a null pointer.
Return directly in this case.
This issue was detected by using the Coccinelle software.
