pageinspect: Fix memory context allocation of page in brin_revmap_data()
This caused the function to fail, as the aligned copy of the raw pagegiven by the function caller was not saved in the correct memorycontext, which needs to be multi_call_memory_ctx in this case.Issue introduced by076f4d9.Per buildfarm members sifika, mylodon and longfin. I have reproducedthat locally with macos.Discussion:https://postgr.es/m/YjFPOtfCW6yLXUeM@paquier.xyzBackpatch-through: 10
