ceph: size handling in MClientRequest, cap updates and inode traces
For encrypted inodes, transmit a rounded-up size to the MDS as the
normal file size and send the real inode size in fscrypt_file field.
Also, fix up creates and truncates to also transmit fscrypt_file.
When we get an inode trace from the MDS, grab the fscrypt_file field if
the inode is encrypted, and use it to populate the i_size field instead
of the regular inode size field.
