Subject: [PATCH 5/8] interconnect: osm-l3: Ignore return value of icc_provider_del() in .remove()

icc_provider_del() already emits an error message on failure. In this
case letting .remove() return the corresponding error code results in
another error message and the device is removed anyhow. (See
platform_remove().)

So ignore the return value of icc_provider_del() and return 0
unconditionally.

This is a preparation for making platform remove callbacks return void.
