Alexey Marchuk 2696886c75 dma: Update translation result to hold iovec pointer
In some cases a single virtually contriguos memory
buffer can be translated to several chunks of memory.
To make such translation possible, update structure
spdk_memory_domain_translation_result to use a pointer
to iovec.
Add a single iov structure or cases where translation
is always 1:1, it will make easier translation callback
implementation. For RDMA transport translation of address
is always 1:1, so treat iovcnt other than 1 as an
error.
