[PATCH 5/7] nics/system_info: Accept memory with unknown speed

[Akihiko Odaki <akihiko.odaki@daynix.com>]

A virtual machine may only have memories with unknown speed. Rejecting
memories with unknown speed cause an exception in such a case because
_strip_memory() expects there is one valid memory at least.
