masm: Don't crash on failed MADV_DONTNEED on Linux
The application could call mlockall(MCL_CURRENT|MCL_FUTURE) to lock all
its memory for performance reasons, causing the madvise call to fail.
There's no need to crash. Instead, manually zero-out the memory when
decommitting.
Fixes: QTBUG-120450
Pick-to: 5.15 6.2 6.5 6.6 6.7
