Namhyung Kim 1e03a26959 perf record: Fix BTF type checks in the off-cpu profiling 
[ Upstream commit 0e501a65d3 ]

The BTF func proto for a tracepoint has one more argument than the
actual tracepoint function since it has a context argument at the
begining.  So it should compare to 5 when the tracepoint has 4
arguments.

  typedef void (*btf_trace_sched_switch)(void *, bool, struct task_struct *, struct task_struct *, unsigned int);

Also, recent change in the perf tool would use a hand-written minimal
vmlinux.h to generate BTF in the skeleton.  So it won't have the info
of the tracepoint.  Anyway it should use the kernel's vmlinux BTF to
check the type in the kernel.

Fixes: b36888f71c ("perf record: Handle argument change in sched_switch")
