scsi: sd: Remove superfluous residual assignments
Since commit 26e85fcd15f6 ("[SCSI] sd: Permit merged discard requests"; kernel v3.10) sd_done() sets the residual not only for failed special requests but also for special requests that succeeded. Hence remove the code from functions called by sd_init_command() that sets the residual. This patch does not change any functionality.
