6.6-stable review patch. If anyone has any objections, please let me know.

From: Song Liu song@kernel.org
commit 300a90b2cb5d442879e6398920c49aebbd5c8e40 upstream.
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.
