i386: fix breakpoints handling in icount mode

Browse Source 
This patch fixes instructions counting when execution is stopped on
breakpoint (e.g. set from gdb). Without a patch extra instruction is translated
and icount is incremented by invalid value (which equals to number of
executed instructions + 1).
