exfat: Downgrade ENAMETOOLONG error message to debug messages

The ENAMETOOLONG error message is printed at each time when user tries
to operate with a too long name, and this can flood the kernel logs
easily, as every user can trigger this.  Let's downgrade this error
message level to a debug message for suppressing the superfluous
logs.
