Subject: Regression in 39461af74125 "bitmap: replace
 bitmap_{from,to}_u32array"

Recently ethtool started to give incomplete values for supported and
advertised modes. There seems to be a regression in this commit:
The bit number parameter in the calls to bitmap_to_arr32() in
store_link_ksettings_for_user() should be __ETHTOOL_LINK_MODE_MASK_NBITS
instead of __ETHTOOL_LINK_MODE_MASK_NU32.

After having changed this ethtool behaves normally again.
