tools: hv: remove unused rte_smp_mb()

Browse Source 
rte_smp_mb() has never been used, and its "static inline __always_inline"
declares inline twice, so clang warns:

  vmbus_bufring.c:61:15: warning: duplicate 'inline' declaration specifier [-Wduplicate-decl-specifier]
  vmbus_bufring.c:62:1: warning: unused function 'rte_smp_mb' [-Wunused-function]

Remove it.
