ceph: allocate sparse_ext map only for sparse reads

[ Upstream commit 18d44c5d062b97b97bb0162d9742440518958dc1 ]

If mounted with sparseread option, ceph_direct_read_write() ends up
making an unnecessarily allocation for O_DIRECT writes.

Fixes: 03bc06c7b0bd ("ceph: add new mount option to enable sparse reads")
