tg3: fix bug caused by uninitialized variable

Browse Source 
The reported bug is caused by using mii_eee_cap1_mod_linkmode_t()
with an uninitialized bitmap. Fix this by zero-initializing the
struct containing the bitmap.

Fixes: 9bc791341bc9a5c22b ("tg3: convert EEE handling to use linkmode bitmaps")
