Andrii Nakryiko 62039c30c1 bpf: Initialize storage pointers to NULL to prevent freeing garbage pointer 
Local storage array isn't initialized, so if cgroup storage allocation fails
for BPF_CGROUP_STORAGE_SHARED, error handling code will attempt to free
uninitialized pointer for BPF_CGROUP_STORAGE_PERCPU storage type. Avoid this
by always initializing storage pointers to NULLs.

Fixes: 8bad74f984 ("bpf: extend cgroup bpf core to allow multiple cgroup storage types")
