Alexey Bataev 119df3803b [OPENMP] Add the test to check that the libomptarget does not cause
infinite loop on removing non-mapped pointer-with-object.

Added test to check that libomptarget does not cause infinite loop when
trying to unmap the pointer-with-object data that was not previously
mapped.
