net: mii: report 0 for unknown lp_advertising

The newly introduced mii_ethtool_get_link_ksettings function sets
lp_advertising to an uninitialized value when BMCR_ANENABLE is not
set:

drivers/net/mii.c: In function 'mii_ethtool_get_link_ksettings':
drivers/net/mii.c:224:2: error: 'lp_advertising' may be used uninitialized in this function [-Werror=maybe-uninitialized]

As documented in include/uapi/linux/ethtool.h, the value is
expected to be zero when we don't know it, so let's initialize
it to that.

Fixes: bc8ee596afe8 ("net: mii: add generic function to support ksetting support")
