CVE-2025-71124: drm/msm/a6xx: move preempt_prepare_postamble after error check
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/a6xx: move preemptpreparepostamble after error check
Move the call to preemptpreparepostamble() after verifying that preemptpostambleptr is valid. If preemptpostambleptr is NULL, dereferencing it in preemptpreparepostamble() would lead to a crash.
This change avoids calling the preparation function when the postamble allocation has failed, preventing potential NULL pointer dereference and ensuring proper error handling.
