fat: FAT filesystem premature release of info struct.
File was found on specified location. Info about file was read, but then immediately destroyed using 'free' call. As a result file size was set to 0, hence fat process didn't read any data. Premature 'free' call removed. Resources are freed right before function return. File is read correctly. Signed-off-by: Martin Vystrcil <martin.vystrcil@m-linux.cz>
