[dpdk-dev] eal: fix C++ build (struct member: virtual)
Commit Message
'virtual' is a keyword and can't be used if the code is to compile with
C++ compilers.
If rte_devargs.h was included in C++ code, compilation with clang++
failed with an error. g++ did not fail, but only because of a bug
that treats it as an anonymous struct with a decl-specifier which it
ignores.
This simply renames the member to 'virt'.

Ack with your signed-off.
