net: phy: mdio-mux: Check return value of mdiobus_alloc()
commit 20b08e1a793d898f0f13040d5418ee0955f678cf upstream.
mdiobus_alloc() might return NULL, but its return value is not
checked in mdio_mux_init(). This could potentially lead to a NULL
pointer dereference. Fix it by checking the return value
