When target claim it support maximum writesame length to the total blocks number, when
we trigger 0blocks writesame opertion, we should expect it to be succeed instread of failure.
This test registers PR key and then sends a PR-In read-keys request with
an ALLOCATION LENGTH value that forces response truncation. Ensure that
the ADDITIONAL LENGTH is *not* modified as a result of the truncation.
This test currently passes against TGT but fails against LIO (fix
pending).

Accepting an Allocation Length parameter allows us to test for
truncation of response data, as per SPC5r17 4.2.5.6:
The device server shall terminate transfers to the Data-In Buffer when
the number of bytes or blocks specified by the ALLOCATION LENGTH field
have been transferred or when all available data have been
transferred, whichever is less.
With this change, all existing prin_read_keys() callers continue to use
same ALLOCATION LENGTH value as earlier (16K).

* Verbose logging segfault fixed.
* For ioctl case, if reservation conflicts hits it is not considered as
test case failure.
Since the data in the read buffer is not valid if READ10() failed,
only compare the data in the read buffer if READ10() succeeded.

Using any of the CU_ASSERT macros after a test has finished causes
the test tool to abort. This patch adds an iSCSI logout to two tests
to avoid that the test tool aborts e.g. as follows:

From SBC-4: BYTCHK = 0 means that the Data-Out buffer contents
must not be used. BYTCHK = 1 means that the Data-Out buffer must
be compared against the data on the storage medium. Hence set
BYTCHK to 1 if EDTL != 0.

ExtendedCopy.DescrLimits currently attempts to test Maximum Descriptor
List Length bounds checking by issuing a request with
(max_target_desc_count + 1 + max_segment_desc_count + 1) descriptors.
Maximum Descriptor List Length is a separately advertised field, that
may not be exceeded with the above logic, e.g. LIO advertises:
- Max Target Desc Count = 2
- Max Segment Desc Count = 1
- Max Desc List Len = 1024
Calculate the number of descriptors using the advertised Maximum
Descriptor List Length value, to explicitly test bounds checking.
