The 'at least one change' requirement is not applicable for context
creation, skip the check in such case.
This allows a command such as 'ethtool -X eth0 context new' to work.
The command works by mistake when using older versions of userspace
ethtool due to an incompatibility issue where rxfh.input_xfrm is passed
as zero (unset) instead of RXH_XFRM_NO_CHANGE as done with recent
userspace. This patch does not try to solve the incompatibility issue.
