Fix memory allocation issue in KPM RAN function sd parameter handling

This fixes a segmentation fault in the gNB when a KPM xApp sends the sd
parameter in the subscription message.

The segmentation fault seems to occur because *sd is uninitialized when
malloc(**sd) is called. This causes a double dereference of an uninitialized
pointer - **sd reads a random memory value which becomes the size parameter
for malloc(), leading to unpredictable memory allocation and segfaults.

This fix allocates the size using malloc(sizeof(uint32_t)) instead of
dereferencing the uninitialized pointer.
