net: usb: asix_devices: Fix PHY address mask in MDIO bus initialization

Syzbot reported shift-out-of-bounds exception on MDIO bus initialization.

The PHY address should be masked to 5 bits (0-31). Without this

mask, invalid PHY addresses could be used, potentially causing issues

with MDIO bus operations.

Fix this by masking the PHY address with 0x1f (31 decimal) to ensure

it stays within the valid range.
