net: qualcomm: rmnet: Allow configuration updates to existing devices
commit 2abb5792387eb188b12051337d5dcd2cba615cb0 upstream.
This allows the changelink operation to succeed if the mux_id was
specified as an argument. Note that the mux_id must match the
existing mux_id of the rmnet device or should be an unused mux_id.
Fixes: 1dc49e9d164c ("net: rmnet: do not allow to change mux id if mux id is duplicated")
