core: dump_ta_memstats(): check TA initialization completion before accessing it

Problem: In some concurrent cases, TA dump will try to
dump a TA which has not completed TA initialization and
the TA stack pointer isn't set. That causes a data abort
when accessing its stack.

Solution: Check the user TA initialization is completed or not.
If it is still being initialized, return TEE_ERROR_BAD_STATE.
