Simon Horman 4c7f3950a9 net: dsa: mv88e6xxx: Correct check for empty list 
Since commit a3c53be55c ("net: dsa: mv88e6xxx: Support multiple MDIO
busses") mv88e6xxx_default_mdio_bus() has checked that the
return value of list_first_entry() is non-NULL.

This appears to be intended to guard against the list chip->mdios being
empty.  However, it is not the correct check as the implementation of
list_first_entry is not designed to return NULL for empty lists.

Instead, use list_first_entry_or_null() which does return NULL if the
list is empty.

Flagged by Smatch.
Compile tested only.
