HDS HNAS driver ignores API value Size when creating a share from snapshot

[Rodrigo Barbieri]

HDS HNAS Manila driver currently creates shares from snapshots using the Size value according to the original share. See following example:

1. Create Share_1 size = 1
2. Create Snapshot_1 from Share_1
3. Extend Share_1 to size = 2
4. Create Share_Snap_1 from Snapshot_1 size = 5
5. Manila DB says size is 5. Looking at the backend, size is 2.

The result is that the backend is inconsistent with what the Manila DB is showing, and is completely ignoring the parameter the user passes in the API.

    Fix HDS HNAS Create from snapshot ignoring Size

    Currently HDS HNAS driver is creating shares from snapshots using
    the size value from the original share, instead of the one the user
    passes through API. This not only makes Manila DB and HNAS Backend
    inconsistent, but also will not be providing the user with the
    share size requested.
