Function htsmsg_get_u32() returns zero on success and an error number on failure. However there are two occurrences in api_epg.c where an error exit is taken when zero is returned.

I have checked all other uses of this function and these are the only cases.

Apologies for not submitting a PR; my limited git knowledge won't handle two PRs outstanding at the same time.
