[PATCH v2] PCI: rcar-ep: Fix the issue of the name parameter when calling devm_request_mem_region

[kingdix10]

From: King Dix <kingdix10@xxxxxx>

When using devm_request_mem_region to request a resource, if the passed
variable is a stack string variable, it will lead to an oops issue when
eecuting the command cat /proc/iomem.

Fix this by replacing outbound_name with the name of the previously
requested resource.
