[PATCH 3/3] kernel-shark: Fix a bug in ksmodel_set_next_bin_edge()

[Yordan Karadzhov <ykaradzhov@vmware.com>]

The modification of the last bin of the model makes no sense (this is
my mistake). The comment above the code that is doing this modification
is partially correct, however it speaks about increasing the size of
the last bin, while the code below the comment changes the lower edge
of this bin. The actual increase of the size of the last bin is done in
ksmodel_set_upper_edge() where the lower edge of the Upper Overflow bin
gets shifted (max + 1). This effectively increases the size of the last bin.
