[PATCH 6.0 0756/1073] perf off_cpu: Fix a typo in BTF tracepoint name, it should be btf_trace_sched_switch

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

From: Namhyung Kim <namhyung@kernel.org>

[ 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")
