Subject: [RHEL7.8 PATCH V2 39/47] Init devlist as an array

devlist is an string. It will change to an array if there is disk that
is sbd disk. If one device is sbd, it runs devlist=().
This line code changes devlist from a string to an array. If there is
no sbd device, it can't run this line code. So it will still be a string.
The later codes need an array, rather than an string. So init devlist
as an array to fix this problem.
