Xiubo Li fb98248fc4 ceph: try to allocate a smaller extent map for sparse read 
[ Upstream commit aaefabc4a5f7ae48682c4d2d5d10faaf95c08eb9 ]

In fscrypt case and for a smaller read length we can predict the
max count of the extent map. And for small read length use cases
this could save some memories.

[ idryomov: squash into a single patch to avoid build break, drop
  redundant variable in ceph_alloc_sparse_ext_map() ]
