target: Add missing WRITE_SAME end-of-device sanity check

commit 8e575c50a171f2579e367a7f778f86477dfdaf49 upstream.

This patch adds a check to sbc_setup_write_same() to verify
the incoming WRITE_SAME LBA + number of blocks does not exceed
past the end-of-device.

Also check for potential LBA wrap-around as well.
