Xiubo Li 524b788758 ceph: always set initial i_blkbits to CEPH_FSCRYPT_BLOCK_SHIFT ...

[ Upstream commit bbb20ea993 ]

The fscrypt code will use i_blkbits to setup ci_data_unit_bits when
allocating the new inode, but ceph will initiate i_blkbits ater when
filling the inode, which is too late. Since ci_data_unit_bits will only
be used by the fscrypt framework so initiating i_blkbits with
CEPH_FSCRYPT_BLOCK_SHIFT is safe.
