FAT write: Fix compile errors
This patch removes compile errors introduced by
commit 9813b750f32c0056f0a35813b9a9ec0f68b664af
'fs/fat: Fix FAT detection to support non-DOS partition tables'
fat_write.c: In function 'disk_write':
fat_write.c:54: error: 'part_offset' undeclared (first use in this function)
fat_write.c:54: error: (Each undeclared identifier is reported only once
fat_write.c:54: error: for each function it appears in.)
fat_write.c: In function 'do_fat_write':
fat_write.c:950: error: 'part_size' undeclared (first use in this function)
These errors only appear when this code is enabled by
defining CONFIG_FAT_WRITE option.
