Subject: [PATCH v1] seccomp: Fix the comment for seccomp_check_filter().

The comment of the seccomp_check_filter() contains a removed function,
seccomp_bpf_load(). This comment needs to be corrected as it may be
misleading to future readers.

seccomp_bpf_load() was removed in the commit bd4cf0ed331a ("net: filter:
rework/optimize internal BPF interpreter's instruction set"). Previously,
seccomp_bpf_load() was used to create an object of struct seccomp_data.
However, this is done inside populate_seccomp_data() now.
