Subject: [PATCH net-next v1 3/3] net: dsa: ksz: ksz8863_smi_probe: set proper return value for ksz_switch_alloc()

ksz_switch_alloc() will return NULL only if allocation is failed. So,
the proper return value is -ENOMEM.

Fixes: 60a364760002 ("net: dsa: microchip: Add Microchip KSZ8863 SMI based driver support")
