mdio: mux: fix an incorrect less than zero error check using a u32
The u32 variable v is being checked to see if an error return is
less than zero and this check has no effect because it is unsigned.
Fix this by making v and int (this also matches the type of
cb->bus_number which is assigned to the value in v).
Detected by CoverityScan, CID#1440454 ("Unsigned compared against zero")
