internal/rm/health: Rename getHealthCheckXids and clarify documentation

getHealthCheckXids's description is inaccurate as getHealthCheckXids actually
returns the XIDs that should be ignored (not considered fatal). Exactly the
opposite of what is written there.

Additionally, the function name itself is a bit ambiguous thus I changed it to
getDisabledHealthCheckXids.
