drm/amdkfd: fix QID bit leak in pqm_create_queue()
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: fix QID bit leak in pqm_create_queue() When MES is enabled and amdgpu_amdkfd_alloc_kernel_mem() fails during the first queue creation for a process, pqm_create_queue() returns early via 'return retval' without going through the err_create_queue cleanup label. This means clear_bit(*qid, pqm->queue_slot_bitmap) is never called, leaving the reserved QID bit permanently set in queue_slot_bitmap. Over time this leaks QID slots, potentially exhausting all available queue slots. Fix this by replacing 'return retval' with 'goto err_allocate_pqn' so that clear_bit() is always called on the error path without touching the uninitialized pqn pointer. AILIKFD-813 (cherry picked from commit a107f74c38edbb80d6ab64dcaeeb292c14e9779f)
