David Disseldorp f934961bf4 scsi: target: avoid per-loop XCOPY buffer allocations ...

[ Upstream commit 0ad08996da05b6b735d4963dceab7d2a4043607c ]

The main target_xcopy_do_work() loop unnecessarily allocates an I/O buffer
with each synchronous READ / WRITE pair. This commit significantly reduces
allocations by reusing the XCOPY I/O buffer when possible.
