[rfc/patch] ntfs reduce syslog noise

[maximilian attems <max@stro.at>]

user complained on syslog spamming by
NTFS-fs error (device hda7): ntfs_ucstonls(): Unicode name contains characters that cannot be converted to character set koi8-r.  You might want to try to use the mount option nls=utf8.
NTFS-fs warning (device hda7): ntfs_filldir(): Skipping unrepresentable inode 0x130cc.
-> http://bugs.debian.org/351009

the custom ntfs loglevel are a pain as they encode the
KERN_ERR printk level for any ntfs_warning() call

belows patch tries to tame one of the 2 complaints.
