mmp: don't assume NUL termination for MMP strings
Don't assume that mmp_nodename and mmp_bdevname are NUL terminated,
since very long node/device names may completely fill the buffers.
Limit string printing to the maximum buffer size for safety, and
change the field definitions to __u8 to make it more clear that
they are not NUL-terminated strings, as is done with other strings
in the superblock that do not have NUL termination.
