bpf: Fix bpf_cgroup_from_id() doxygen header
In commit 332ea1f697be ("bpf: Add bpf_cgroup_from_id() kfunc"), a new
bpf_cgroup_from_id() kfunc was added which allows a BPF program to
lookup and acquire a reference to a cgroup from a cgroup id. The
commit's doxygen comment seems to have copy-pasted fields, which causes
BPF kfunc helper documentation to fail to render:
<snip>/helpers.c:2114: warning: Excess function parameter 'cgrp'...
<snip>/helpers.c:2114: warning: Excess function parameter 'level'...
<snip>
<snip>/helpers.c:2114: warning: Excess function parameter 'level'...
This patch fixes the doxygen header.
Fixes: 332ea1f697be ("bpf: Add bpf_cgroup_from_id() kfunc")
