Subject: target/iscsi: Remove dead code from iscsit_process_scsi_cmd()
Git-commit: 8fa4011e0dd9423f1226f2f9769a1cf25c264468
Patch-mainline: v4.13-rc1
References: fate#323946

If an iSCSI command is rejected before iscsit_process_scsi_cmd()
is called, .reject_reason is set but iscsit_process_scsi_cmd() is
not called. This means that the "if (cmd->reject_reason) ..." code
in this function can be removed without changing the behavior of
this function.
