lib-fs-resize: Prevent crash resizing FAT16 file systems
Resizing FAT16 file system crashes in libparted/fs/r/fat/resize.c
create_resize_context() because it was dereferencing NULL pointer
fs_info->info_sector to copy the info_sector.
Only FAT32 file systems have info_sector populated by fat_open() ->
fat_info_sector_read(). FAT12 and FAT16 file systems don't have an
info_sector so pointer fs_info->info_sector remains assigned NULL from
fat_alloc(). When resizing a FAT file system create_resize_context()
was always dereferencing fs_info->info_sector to memory copy the
info_sector, hence it crashed for FAT12 and FAT16.
Make create_resize_context() only copy the info_sector for FAT32 file
systems.
