memory-device: Fix memory pre-plug error API violations
memory_device_get_free_addr() dereferences @errp when
memory_device_check_addable() fails. That's wrong; see the big
comment in error.h. Introduced in commit 1b6d6af21b "pc-dimm: factor
out capacity and slot checks into MemoryDevice".
No caller actually passes null.
Fix anyway: splice in a local Error *err, and error_propagate().
