If no available resource pool, we still can create snapshot and active it. But the snapshot will stop automatically if IOs writed to the src LUN. In this situation, we will failed to create snap volume. The driver should check whether resource pool is available when creating snapshot.

Fix bugs for Huawei driver
This fixes two bugs for Huawei iscsi driver.
(1)If firstly we map LUN 1(just not LUN 0) to host,we can also
find LUN 0 mapped,whose device path is '-'.Then we will failed
to map a real LUN 0.So,we avoid mapping LUN 0 to host by setting
every volume's host LUN ID larger than 0,instead of generating it
automatically.
(2)Check valid size of resource pools when creating snapshot and
make sure it larger than 1 GB.
