scsi: core: Fix capacity set to zero after offlinining device
After adding physical volumes to a volume group through vgextend, the
kernel will rescan the partitions. This in turn will cause the device
capacity to be queried.
If the device status is set to offline through sysfs at this time, READ
CAPACITY command will return a result which the host byte is
DID_NO_CONNECT, and the capacity of the device will be set to zero in
read_capacity_error(). After setting device status back to running, the
capacity of the device will remain stuck at zero.
Fix this issue by rescanning device when the device state changes to
SDEV_RUNNING.
