drm/amd/display: Move the memory allocation out of dcn21_validate_bandwidth_fp().
dcn21_validate_bandwidth_fp() is invoked while FPU access has been
enabled. FPU access requires disabling preemption even on PREEMPT_RT.
It is not possible to allocate memory with disabled preemption even with
GFP_ATOMIC on PREEMPT_RT.
Move the memory allocation before FPU access is enabled.
