perf off_cpu: Fix a typo in BTF tracepoint name, it should be 'btf_trace_sched_switch'
[ Upstream commit 167b266bf66c5b93171011ef9d1f09b070c2c537 ]
In BTF, tracepoint definitions have the "btf_trace_" prefix. The
off-cpu profiler needs to check the signature of the sched_switch event
using that definition. But there's a typo (s/bpf/btf/) so it failed
always.
Fixes: b36888f71c8542cd ("perf record: Handle argument change in sched_switch")
