libertas: EHS_REMOVE_WAKEUP is not always supported
Certain firmware versions, particularly the 8388 found on the XO-1,
do not support the EHS_REMOVE_WAKEUP command that is used to disable
WOL. Sending this command to the card will return a failure that
would get propagated up the stack and cause suspend to fail.
Instead, fall back to an all-zero wakeup mask.
