[PATCH] scsi_debug: test always evaluates to false, || should be used instead

[Colin King <colin.king@canonical.com>]

From: Colin Ian King <colin.king@canonical.com>

cppcheck found the following issue:
(warning) Logical conjunction always evaluates to false:
  alloc_len < 4 && alloc_len > 65535.

..the test should be instead:

  if (alloc_len < 4 || alloc_len > 65536)

This error was introduced by recent commit 38d5c8336e60bf6e53a1da9
("scsi_debug: add Report supported opcodes+tmfs; Compare and write")
