fat: fix FAT sector offsets overflow on large FAT partitions
This patch fixes several issues where sector offsets can overflow due
to being limited to 16-bits. The cases where an overflow can happen
when accessing large FAT32 partitions are:
- length of FAT in sectors
- start sector of root directory
- the sector of the first cluster
These issues were observed when reading files from a 64GB FAT32
filesystem.
