Jitendra Bhivare 4788e732c3 scsi: be2iscsi: Modify IOCTL to fetch user configured IQN
Add version 1 of GET_HBA_NAME to fetch port specific IQN first.
If it fails use version 0 to get the IQN.

To use this old IQN names of interfaces needs to be cleared from

The accesses to beiscsi_io_task is being protected in device reset handler
with frwd_lock but the freeing of task can happen under back_lock.

Hold the reference of iscsi_task till invalidation completes.
This prevents use of ICD when invalidation of that ICD is being processed.

beiscsi_io_task structures.

Jitendra Bhivare 50a4b824be scsi: be2iscsi: Fix to make boot discovery non-blocking
Boot work involves:
1. Find and fetch configured boot session and its handle.
2. Attempt to open the session if its not.
3. Get the session details for boot kset creation.
4. Logout of that session owned by FW.
5. Create boot kset for session details.

All these actions were done in blocking call with retries in global wq.
Other works in wq suffered if the IOCTLs stalled or timed out.

This change moves all the boot work to make it non-blocking.
The work queued in global wq just issues the IOCTL depending on the action
to be taken and mcc wq schedules work depending on status of the IOCTL.
Initial boot_work is started on link and ASYNC event.

The other code changes move all boot related functions in one place and
follow naming conventions.

Mike Christie a41a9ad3bb be2iscsi: check ip buffer before copying
Dan Carpenter found a issue where be2iscsi would copy the ip
from userspace to the driver buffer before checking the len
of the data being copied:
http://marc.info/?l=linux-scsi&m=140982651504251&w=2

This patch just has us only copy what we the driver buffer
can support.
