IB/uverbs: Set error code when fail to consume all flow_spec items
If the flow_spec items parsed count does not match the number of items
declared in the flow_attr command, or if not all bytes are used for
flow_spec items (eg. trailing garbage), a log message is reported and
the function leave through the error path. Unfortunately the error
code is currently not set.
This patch set error code to -EINVAL in such cases, so that the error
is reported to userspace instead of silently fail.
