perf tests stat+csv_output: Fix shellcheck warnings
Running the shellcheck on stat+csv_output resulted in the following
warning.
Result with shellcheck without patch:
=====
$ shellcheck -S warning stat+csv_output.sh
In stat+csv_output.sh line 23:
[ $(uname -m) = "s390x" ] && exp='^[6-7]$'
^---------^ SC2046: Quote this to prevent word splitting.
In stat+csv_output.sh line 51:
[ $(id -u) != 0 ] && [ $(cat /proc/sys/kernel/perf_event_paranoid) -gt $1 ]
^------^ SC2046: Quote this to prevent word splitting.
^-- SC2046: Quote this to prevent word splitting.
=====
Fixed the warning SC2046 by adding quotes to prevent word splitting.
Result with shellcheck with patch:
=====
$ shellcheck -S warning tests/shell/stat+csv_output.sh
$ ./perf test "stat CSV output linter"
96: perf stat CSV output linter : Ok
