drm/amdgpu: Send applicable RMA CPERs at end of RAS init

Browse source 
Firmware and monitoring tools may not be ready to receive a CPER when we
read the bad pages, so send the CPERs at the end of RAS initialization
to ensure that the FW is ready to receive and process the CPER. This
removes the previous CPER submission that was added during bad page
load, and sends both in-band and out-of-band at the same time.
