[LEDE-DEV] [PATCH][V2][netifd] ubus: propagate error code on netifd_reload()

The context is that we generate some of the UCI config
for netifd via scripts/programs.
Every once in a while, there's a goof when doing that
UCI generation, and netifd prints out the error at
stderr, but returns 0 (success) err-code.
This change will fail the ubus call if UCI config
is invalid for /etc/config/network & /etc/config/wireless,
or could not be loaded (via uci_load()).
Admittedly, failing the entire ubus call could
be a bit much [depending on various views].
Probably one idea, would be to return the err-code
as a ubus reply data (via ubus_send_reply()).
Not sure.
