scsi: core: Fix the scsi_set_resid() documentation

commit f669b8a6 upstream.

Because scsi_finish_command() subtracts the residual from the buffer
length, residual overflows must not be reported. Reflect this in the SCSI
documentation. See also commit 9237f04e ("scsi: core: Fix
scsi_get/set_resid() interface")
