Manivannan Sadhasivam 01836e56fd bus: mhi: ep: Save channel state locally during suspend and resume
commit 8a1c24bb90 upstream.

During suspend and resume, the channel state needs to be saved locally.
Otherwise, the endpoint may access the channels while they were being
suspended and causing access violations.

Fix it by saving the channel state locally during suspend and resume.
