hwthread: Add register validity check in get_thread_reg_list

When OpenOCD receives 'g' packet (read general registers) from GDB and
target is configured as rtos=hwthread, hwthread_get_thread_reg_list is
called. However, it does not check if the register valid or not. Due to
this issue, OpenOCD returns invalid register values to GDB.
This commit adds a validity check to hwthread_get_thread_reg_list. If
the register is not valid, it tries to read the register from the
target.
