WLAN: Reset power save mode to startup value after DHCP response.
When the driver was configured to run with power save mode disabled the
power save mode incorrectly got reverted back to AUTO mode right after
DHCP response. The power save mode value is now saved so that the device
properly reverts back to a previous mode after DHCP response.
