Add default configuration for ZXUSP series products of ZTE SAN storage such as KS3200, KS5200.

…by CLI

We fail a path, and suspend the map which the path belongs to, then reinstate the path by CLI and it returned with a fail message, the problem is: 1) There is a lot of log messages that indicate the path status is up but reinstate fail; 2) When we resume the map, the path change status to active from failed automatically though it's failed when we reinstated path before.

Problem:
Multipathd segment faulty occured when device policy was configured in multipath.conf as follow:
#This is a device configuration just for COMPELNT device
devices {
       device {
               vendor                  COMPELNT
               dev_loss_tmo            120
               scheduler               deadline
       }
}

The call trace is:
Program received signal SIGSEGV, Segmentation fault.

Reasons:
When multipathd loads config, it will call merge_hwe() to merge the features between default_hw[] and config.
If the vender is not configured features in default_hw[], dst->features's value will be null. So strstr()'s first
parameter *f is null in add_feature(),too.

@JunhuiTang, I can pull the hwhandler part, but I suppose the rest is outdated. In general, please send patches to the [email protected] mailing list rather than here.
