[OpenMP52][LIBOMPTARGET] Do not throw error in omp_get_mapped_ptr for the host

[saiislam]

OpenMP spec 5.2 specifies return value to be the host ptr
in case of device_num being same as omp_get_initial_device().

[carlobertolli]

That is the correct interpretation of the OpenMP spec text. LGTM, waiting for @shiltian to review
