e1000e: Fix comment for the function, e1000e_setup_copper_link

This changes the comment about checking link status to state that we wait at least 10 microseconds rather then 100 as the third agrument passed to the function, e1000e_phy_has_link_generic for time delayed in microseconds is not 100 but 10 in this particular call to the function.
