[media] rc-main: store_filter: pass errors to userland
Propagate errors returned by drivers from the s_filter callback back to userland when updating scancode filters. This allows userland to see when the filter couldn't be updated, usually because it's not a valid filter for the hardware. Previously the filter was being updated conditionally on success of s_filter, but the write always reported success back to userland.
