Qla4xxx can just call the iscsi recovery functions directly.
There is no need for userspace to do this for qla4xxx, because
we do not use the mutex to iterate over devices anymore and iscsi_block
/unblock_session can be called from interrupt context or the dpc thread.
And having userspace do this just creates uneeded headaches for qla4xxx root
situations where the session may experience problems. For example
during the kernel shutdown the scsi layer wants to send sync caches, but at
this time userspace is not up (iscsid is not running), so we cannot
recover from the problem.

It should be desired that 64 KiB is available for ATAPI transferrring.
(Historically) in SCSI/block layer sector size is defined as 512 during
sector-byte calculation.
Originally in ps3rom.c CD_FRAMESIZE (2048) was used, which limited
/sys/block/sr0/queue/max_sectors_kb to 16 KiB (32 sectors).

The "whole_disk" attribute was not properly converted in the block
