net: usb: lan78xx: Fix refcounting and autosuspend on invalid WoL configuration
[ Upstream commit e863ff806f72098bccaf8fa89c80d9ad6187c3b0 ]
Validate Wake-on-LAN (WoL) options in `lan78xx_set_wol` before calling
`usb_autopm_get_interface`. This prevents USB autopm refcounting issues
and ensures the adapter can properly enter autosuspend when invalid WoL
options are provided.
Fixes: eb9ad088f966 ("lan78xx: Check for supported Wake-on-LAN modes")
