Andrii Nakryiko 12cc126df8 bpf: Fix bpf_put_raw_tracepoint()'s use of __module_address() ...

__module_address() needs to be called with preemption disabled or with
module_mutex taken. preempt_disable() is enough for read-only uses, which is
what this fix does. Also, module_put() does internal check for NULL, so drop
it as well.

Fixes: a38d1107f9 ("bpf: support raw tracepoints in modules")
