ethtool: Remove trailing semicolon for static inline

[ Upstream commit d89d41556141a527030a15233135ba622ba3350d ]

Android's header sanitization tool chokes on static inline functions having a
trailing semicolon, leading to an incorrectly parsed header file. While the
tool should obviously be fixed, also fix the header files for the two affected
functions: ethtool_get_flow_spec_ring() and ethtool_get_flow_spec_ring_vf().

Fixes: 8cf6f497 ("ethtool: Add helper routines to pass vf to rx_flow_spec")
