target-xtensa: fix CCOUNT for conditional branches

Taken conditional branches fail to update CCOUNT register because
accumulated ccount_delta is reset during translation of non-taken
branch. To fix it only update CCOUNT once per conditional branch
instruction translation.

This fixes guest linux freeze on LTP waitpid06 test.
