Currently, the user mode abort and some system calls return to kernel
mode by thread_exit_user_mode(). Although this function creates a
shorter path to return to kernel mode, it leads to some problems because
the function does not update the core local flags. Especially when
CFG_CORE_DEBUG_CHECK_STACKS=y, some checks will fail due to wrong type
of stack recorded in the core local flags.
Fix it by removing thread_exit_user_mode(). So that the core local flags
can be correctly updated in the common trap handler.
