bpf: net_sched: Fix using bpf qdisc as default qdisc
Use bpf_try_module_get()/bpf_module_put() instead of try_module_get()/
module_put() when handling default qdisc since users can assign a bpf
qdisc to it.
To trigger the bug:
$ bpftool struct_ops register bpf_qdisc_fq.bpf.o /sys/fs/bpf
$ echo bpf_fq > /proc/sys/net/core/default_qdisc
Fixes: c8240344956e ("bpf: net_sched: Support implementation of Qdisc_ops in bpf")
