net: usb: rtl8150 fix unintiatilzed variables in rtl8150_get_link_ksettings
[ Upstream commit fba383985354e83474f95f36d7c65feb75dba19d ]
This functions retrieves values by passing a pointer. As the function
that retrieves them can fail before touching the pointers, the variables
must be initialized.
