ceph: Fix incorrect flush end position calculation

Browse Source 
[ Upstream commit f452a22046 ]

In ceph, in fill_fscrypt_truncate(), the end flush position is calculated
by:

                loff_t lend = orig_pos + CEPH_FSCRYPT_BLOCK_SHIFT - 1;

but that's using the block shift not the block size.

Fix this to use the block size instead.
