mm: mem alloc: Use SLUB instaed SLQB/SLAB memory allocator
During my tests I experienced one single random reboot on sound playback when using SLQB instead SLAB. But after this reboot I never had any problem anymore. But many users reported about random reboots caused by sound playback, and it didn't 'fix' itself like mine. As kexec doesn't have a working apanic label, we cannot track down the issue via log, so now disable SLQB and use SLUB as SLAB is deprecated and outdated as well.

This will be pushed as 'emergency' update build via OTA to fix random reboots for all users being on latest build.

The SLQB-build will be available as EXPERIMENTAL release for those who can run it w/o issues, just like me. We have to investigate what's causing these reboots for most users and why does it work for me and some single users.
