[PATCH v4 1/4] eal: fix macro for versioned experimental symbol

[Dariusz Sosnowski]

Add a missing semicolon after __asm__ block in
RTE_VERSION_EXPERIMENTAL_SYMBOL macro.
It's lack triggers the following compilation error with clang:

    ../lib/ethdev/rte_flow.c:320:1: error: expected ';' after top-level asm block
      320 | RTE_VERSION_EXPERIMENTAL_SYMBOL(int, rte_flow_dynf_metadata_register, (void))
          | ^
    ../lib/eal/common/eal_export.h:75:74: note: expanded from macro 'RTE_VERSION_EXPERIMENTAL_SYMBOL'
       75 | __asm__(".symver " RTE_STR(name) "_exp, " RTE_STR(name) "@EXPERIMENTAL") \
          |                                                                          ^
    ../lib/eal/include/rte_common.h:237:20: note: expanded from macro '\
    __rte_used'
      237 | #define __rte_used __attribute__((used))
          |                    ^
