specifying log_compression results in log_avg_msec ignored for bw and iops logs

[Rogach]

Please acknowledge the following before creating a ticket

• [x] I have read the GitHub issues section of REPORTING-BUGS.

Description of the bug: If log_compression is specified together with log_avg_msec, then bw and iops logs still contain a separate entry for each I/O done (instead of averages as expected).

Environment: Arch Linux, 6.7.5-arch1-1

fio version: fio-3.37

Reproduction steps

[global]
size=1TB

kb_base=1000
ioengine=libaio
invalidate=1
direct=1

write_bw_log
write_iops_log
write_lat_log
log_compression=128MiB
log_avg_msec=10

[test]
rw=read
io_limit=2GiB
iodepth=64

Run with fio --filename /dev/sdX test.fio.

Observe lots of non-averaged entries in the bw and iops logs:
