perf tests: Fix shellcheck warning in record_sideband.sh
Running shellcheck on record_sideband.sh throws below
warning:
In tests/shell/record_sideband.sh line 25:
if ! perf record -o ${perfdata} -BN --no-bpf-event -C $1 true 2>&1 >/dev/null
^--^ SC2069: To redirect stdout+stderr, 2>&1 must be last (or use '{ cmd > file; } 2>&1' to clarify).
This shows shellcheck warning SC2069 where the redirection
order needs to be fixed. Use "cmd > /dev/null 2>&1" to fix
the redirection of perf record output
Fixes: 23b97c7ee963 ("perf test: Add test case for record sideband events")
