Fix copy-paste error related to the autovacuum launcher in pgstat_io.c Autovacuum launchers perform no WAL IO reads, but pgstat_tracks_io_op() was tracking them as an allowed combination for the "init" and "normal" contexts.
This caused the "read", "read_bytes" and "read_time" attributes of pg_stat_io to show zeros for the autovacuum launcher rather than NULL. NULL means that a combination of IO object, IO context and IO operation has no meaning for a backend type. Zero is the same as telling that a combination is relevant, and that WAL reads are possible in an autovacuum launcher, but it is not relevant. Copy-pasto introduced in a051e71e28a1.
