usb_blaster: Don't unnecessarily go through DR-/IR-Pause

There is no need to pass through DR-/IR-Pause after a scan if we want to
go to DR-/IR-Update. We just have to skip the first step of the path to
the end state because we already did that step when shifting the last
bit.

v2:
 - Fix comments as remarked in review of v1
