Correctly report usage of absolutely full NTFS (#697946) 

For an absolutely full NTFS GParted doesn't show the file system usage
but instead shows a warning against the partition.

GParted was looking only for "resize at %d" to determine file system
used figure in the output from the ntfsresize command.  Also handle
finding "ERROR: Volume is full" too to derive used figure.

NTFS with 1 block free case:
    # ntfsresize --info --force --no-progress-bar /dev/sda9
    ...
    Current volume size: 1073738240 bytes (1074 MB)
    ...
    Collecting resizing constraints ...
    You might resize at 1073737728 bytes (freeing 4096 bytes).
    ...
    # echo $?
    0

Absolutely full NTFS case:
    # ntfsresize --info --force --no-progress-bar /dev/sda9
    ...
    Current volume size: 1073738240 bytes (1074 MB)
    ...
    Collecting resizing constraints ...
    ERROR: Volume is full. To shrink it, delete unused files.
    # echo $?
    1
