msdosfs: fix #3237 where reading the last sector of a file returned 0s
cluster_readx would load the correct data to cache except for the last
sector of a file, where the cache was filled with zeroes.
On small files (2 clusters) cluster_readx wouldn't even call
msdosfs_bmap, correctly read first cluster and return zeroes for the
second cluster.
Fix this by telling cluster_readx that the file is bigger than it
is. cluster_readx's `nblk` will then include the last sector.
