net: qualcomm: rmnet: Fix possible null dereference in command processing

Browse source

If a command packet with invalid mux id is received, the packet would
not have a valid endpoint. This invalid endpoint maybe dereferenced
leading to a crash. Identified by manual code inspection.

Fixes: 3352e6c457 ("net: qualcomm: rmnet: Convert the muxed endpoint to hlist")
