If there is no write I/O between removing member disk and re-add it, there is no
recovery after re-adding member disk.

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.

Fixes: beb71de04d ("mdadm/test: enable clustermd testing under clustermd_tests/")
clustermd_tests/func.sh:
remove unnecessary 'make install', just ensure 'make everything' has done.
the original idea is to make the /sbin/mdadm version same as ./mdadm, and
this breakage has pointed out by commit:
59416da78f ("tests/func.sh: Fix some total breakage in the test scripts")

03r10_switch-recovery:
Create new array with 2 active and 1 spare disk, set 1 active disk as 'fail',
it triggers recovery and the spare disk would replace the failure disk, then
stop the array in doing recovery node, the other node would take it over and
continue to complete the recovery.

For clustermd testing, it needs user deploys the basic cluster
manually, test scripts don't cover auto-deploy cluster due to
different linux distributions have lots of difference.
Then complete the configuration in cluster_conf, please refer to
the detail comments in 'cluster_conf'.
1. 'func.sh' source file, it achieves feature functions for
clustermd testing.
2. 'cluster_conf' configure file, it contains two parts as
the input of testing.
