scst_mem: Fix a memory leak triggered by the scst_user driver
Avoid that the following memory leak can occur:
- sgv_pool_alloc() is called with SGV_POOL_RETURN_OBJ_ON_ALLOC_FAIL
set, with neither SGV_POOL_NO_ALLOC_ON_CACHE_MISS nor
SGV_POOL_ALLOC_NO_CACHED set and with 'size' such that
sgv_max_local_pages < pages_to_alloc <= pool->max_cached_pages.
- sgv_get_obj() and sgv_alloc_arrays() succeed.
- sgv_alloc_sg_entries() fails.
- sgv_get_obj() returns the SGV object with no buffers.
- A call to sgv_pool_free() adds this object to the recycle list.
- sgv_pool_alloc() is called a second time with the same parameters.
- sgv_get_obj() retrieves the object that was previously added to
the recycle list.
- sgv_alloc_arrays() is called and overwrites the obj->sg_entries
pointer although it still points at allocated memory, resulting
in a memory leak.

scst_local: Change max_lun into SCST_MAX_LUN (16383)
Today SCST does not support LUN numbers >= 16384. Additionally,
there is a bug in older Linux initiator systems that prevents
proper handling of LUN numbers >= 2**32. See also Hannes Reinecke,

vdisk_blockio: Make large COMPARE AND WRITE requests work for stacked block devices
Stacked block devices impose weird restrictions on S/G-lists. Hence
make the COMPARE AND WRITE implementation independent of these
restrictions.
Additionally, reduce the MAXIMUM COMPARE AND WRITE LENGTH limit from
0xff (no limit) to 0xfe to reduce the maximum amount of memory allocated
during a COMPARE AND WRITE. Also serialize COMPARE AND WRITE
operations, fix the offset reported for miscompares and fix the start
offset of the region that is synchronized if the FUA bit has been set.

Rename the static one so that it will be less confusing while reading the code.
