librmnetctl: Fix incorrect handling of messages with return type data
When an message with return type data fails in kernel, the error
is handled incorrectly.
Consider a scenario when we try to query the vnd name corresponding
to a non existent vnd id.
/ # rmnetcli getvndname 25
rmnetcli getvndname 25
LIBRARY ERROR: Return type is invalid
We appear to be getting a library error even though the actual
error originates from the kernel. The actual error for this case
should be a kernel error and the return code should be Invalid
request / Unsupported scenario.
Fix this by checking for return codes in case there is an error
when a return data type fails.
