iscsi-target: Fix uninitialized usage of cmd->pad_bytes
This patch fixes an uninitialized usage of cmd->pad_bytes inside of iscsit_handle_text_cmd() introduced during a v4.1 change to use cmd members instead of local pad_bytes variables. Reported-by: Dan Carpenter <error27@gmail.com> Signed-off-by: Nicholas Bellinger <nab@linux-iscsi.org>
