[LTP] [PATCH 1/6] tst_test: Allow priting TINFO without initialized IPC

[Cyril Hrubis]

If we try to print TINFO messages while the shared memory to store
results is not initialized we stop the test execution with TBROK.

But we do not store anything on TINFO hence it does not make much sense
to exit at this point.

The motivation for this change is that test library code that prints
messages with TINFO (tst_device.c for instance) cannot be used without
doing full test initialization, which is unfortunate since I wanted to
reuse the code to create a helper binary for shell testcases.
