net: usb: asix: ax88772_bind return error when hw_reset fail
The ax88772_bind() should return error code immediately when the PHY
was not reset properly through ax88772a_hw_reset().
Otherwise, The asix_get_phyid() will block when get the PHY
Identifier from the PHYSID1 MII registers through asix_mdio_read()
due to the PHY isn't ready. Furthermore, it will produce a lot of
error message cause system crash.As follows:
asix 1-1:1.0 (unnamed net_device) (uninitialized): Failed to write
reg index 0x0000: -71
asix 1-1:1.0 (unnamed net_device) (uninitialized): Failed to send
software reset: ffffffb9
