fstab: rework and tune down some flags

errors=panic seems to be causing issues with certain S-ON devices.
No clue why, just disable it for now.

kill devlog partition and HTC logger

Turns out S-ON prevents formatting devlog partition. That partition also
raises FS errors for some users which combined with errors=panic mount
flag will cause unnecessary reboots.

I don't think it's wise to use a partition which raises FS errors and
while it can't be reformatted I think it's best to disable it
altogether.

I haven't been a big fan of using blackbox logger either so the little
practicality HTC logger provides is not worth to flip the scales to
using broken partition.

Thanks dr.patron99 for testing help with S-ON.
