[patch] adv_pci1710 and start_src=TRIG_EXT

• From: Nils Juergens <ju_at_isf.rwth-aachen.de>

Hello again,

in the case of a command with start_src=TRIG_EXT, the Control_CNT0 control
bit is overwritten when interrupt_service_pci1710() switches from TRIG_EXT to
TRIG_xxx.

This patch fixes that. Please apply :)

thanks,

Nils
