bug(ami): setup-local-disks script fails when called with "none" as argument

[vflaux]

What happened:
setup-local-disks script fails when called with "none" as argument due to a missing "echo".

sh-4.2$ sudo setup-local-disks none
/bin/setup-local-disks: line 240: disk setup is 'none', nothing to do!: command not found
Exited with error on line 240
sh-4.2$ echo $?
127

amazon-eks-ami/templates/shared/runtime/bin/setup-local-disks

Lines 239 to 242 in aa23e40

	if [ "${DISK_SETUP}" = "none" ]; then
	"disk setup is 'none', nothing to do!"
	exit 0
	fi

What you expected to happen:
The error message and exit code 0.

How to reproduce it (as minimally and precisely as possible):

Execute sudo setup-local-disks none from an instance.

Environment:

• AWS Region: N/A
• Instance Type(s): N/A
