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.
