net: mctp: usb: Improve IN endpoint status handling

Browse source

Currently, we give-up on all non-zero status values on our IN/rx urb,
and do not re-queue the urb. This will stall the driver, and prevent
any further receive.

Instead, attempt a re-queue on transient errors, with a max of ten
successive failures. Handle EPIPE specially, by scheduling a
usb_clear_halt() in non-atomic context.
