drm/amd/display: Disable migration to ensure consistency of per-CPU variable
[why]
Since the variable fpu_recursion_depth is per-CPU type, it has one copy
on each CPU, thread migration causes data consistency issue, then the
call trace shows up. And preemption disabling can't prevent migration.
[how]
Disable migration to ensure consistency of fpu_recursion_depth.
