kernel: drm/amd/display: Use krealloc_array() in dal_vector_reserve()

A flaw was found in the Linux kernel's drm/amd/display component. The dalvectorreserve function calculates memory allocation size using 32-bit arithmetic, which can lead to an integer overflow. This overflow causes a smaller memory buffer to be allocated than intended, resulting in a heap overflo...
