fs/ntfs3: Add hidedotfiles to the list of enabled mount options

Currently, the ntfs3 driver does return the hidedotfiles mount
option in the list of enabled mount options. This can confuse
users who may doubt they enabled the option when not seeing in
the list provided by the mount command.

Add hidedotfiles mount option to the list of enabled options
provided by the mount command when it is enabled.
