Igor Mammedov c9f4b77ad5 pc-dimm: fix error handling in pc_dimm_check_memdev_is_busy()
If host_memory_backend_get_memory() were to return error and
NULL MemoryRegion, pc_dimm_check_memdev_is_busy() would crash
dereferencing NULL pointer in memory_region_is_mapped().
But if error is set and non NULL MemoryRegion is returned
then error_setg() will fail with "error already set" assertion
in error_setv()

To avoid above issues use typical error handling pattern
for property setters:

Error *local_error = NULL;
...
error_propagate(errp, local_err);
