[PATCH bpf-next] bpf: lsm: Set bpf_lsm_blob_sizes.lbs_task to 0

[Song Liu <song@kernel.org>]

bpf task local storage is now using task_struct->bpf_storage, so
bpf_lsm_blob_sizes.lbs_task is no longer needed. Remove it to save some
memory.

Fixes: a10787e6d58c ("bpf: Enable task local storage for tracing programs")
