net: bpfilter: fallback to netfilter if failed to load bpfilter kernel module
If bpfilter is not available return ENOPROTOOPT to fallback to netfilter.
Function request_module() returns both errors and userspace exit codes.
Just ignore them. Rechecking bpfilter_ops is enough.
Fixes: d2ba09c17a06 ("net: add skeleton of bpfilter kernel module")
