Skip all delays in probe_jedec() if probe_delay is 0
Probe_jedec() checks the delay value and issues programmer_delay based
on the value except for delays between single chip_writeb. If a chip has
zero probe_delay, delays between chip_writeb should be skipped as well.
Corresponding to flashrom svn r805.
