[CRIU] [PATCH 2/2] tty: Fix false-positive failure if index of peer is zero

[Cyrill Gorcunov]

Plain __is_log2 is not enough here since a peer with index 1
is a master peer, but __is_log2 treat it as power of two
value for obvious reason, which in turn makes code to thing
we've met slave peer, wrongly of course.

So use is_slave_index helper wich would not only call for
proper is_log2 but take a slave peer with index 0 into
account as well.
