arm64: perf: fix event validation for software group leaders
commit ee7538a008a45050c8f706d38b600f55953169f9 upstream.
This is a port of c95eb3184ea1 ("ARM: 7809/1: perf: fix event validation
for software group leaders") to arm64, which fixes a panic in the arm64
perf backend found as a result of Vince's fuzzing tool.
