Add MDIC_WA and CLSEMWA to snprintb() string for WM_F_* flags.

Fix two bugs for non-SERDES fiber. Tested on 82544EI(0x1009), 82545GM(0x1027),
82546GB(0x107a), 82571GB(0x105f), 82572EI(0x107e). Tested on SERDES
82580(0x150e (Winyao SERDES SFP)) and 82580(0x150e) as regression test:

- Fix a bug that the link can't detect in link interrupt function for
   non-SERDES fiber. When the signal is detected & STATUS_LU == 0 & RXCW == 0,
   it's required to set CTRL_SLU and CTRL_FD bit. wm_check_for_link() is the
   function to do it. If a link status change interrupt occurred, call
   wm_check_for_link() before checking current link status.

- Fix a bug that 82542 misunderstand fiber's signal detection. CTRL_SWDPIN(1)
   is used for fiber's signal and it's value is reversed only on 82543 and
   82544. Simplify the code and move it into a new function wm_tbi_havesignal()
   and use it.
