e1000e: fix acquisition of SW/FW/HW semaphore for ICHx parts

For ICHx parts, write the EXTCNF_CTRL.SWFLAG bit once when trying to
acquire the SW/FW/HW semaphore instead of multiple times to prevent the
hardware from having problems (especially for systems with manageability
enabled), and extend the timeout for the hardware to set the SWFLAG bit.
