[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.
