Cast Integer Argument To Unsigned Char

The member reg in the peercnt structure is an unsigned char and peercnt_modify()
is expecting an unsigned char argument which gets assigned to peercnt->reg.

This patch fixes that by casting the integer argument being passed to
peercnt_modify to unsigned char.
