mpol_to_str() should not fail. Currently, it either fails because the
string buffer is too small or because a string hasn't been defined for a
mempolicy mode.
If a new mempolicy mode is introduced and no string is defined for it,
just warn and return "unknown".
If the buffer is too small, just truncate the string and return, the
same behavior as snprintf().
This also fixes a bug where there was no NULL-byte termination when doing
*p++ = '=' and *p++ ':' and maxlen has been reached.
