net/bnx2x: fix link state

Don't call bnx2x_link_status_update() from bnx2x_link_update().
Actual use case of bnx2x_link_status_update() is to update the link
status in shared memory between driver and MFW, and not to get the
link status from HW.

So ideally, bnx2x_link_status_update() should be called when there
is an actual link event or change in link status.

Calling bnx2x_link_status_update() from bnx2x_link_update() may
corrupt the data of link status in shared memory and result
in inconsistent state of link.
