CVE-2025-68744

bpf: Free special fields when update [lru_,]percpu_hash maps

In the Linux kernel, the following vulnerability has been resolved:

bpf: Free special fields when update [lru_,]percpu_hash maps

As [lru_,]percpu_hash maps support BPF_KPTR_{REF,PERCPU}, missing
calls to 'bpf_obj_free_fields()' in 'pcpu_copy_value()' could cause the
memory referenced by BPF_KPTR_{REF,PERCPU} fields to be held until the
map gets freed.

Fix this by calling 'bpf_obj_free_fields()' after
'copy_map_value[,_long]()' in 'pcpu_copy_value()'.
