[PATCH] rte_pci.h: Fix C++11 compilation

[Stefan Puiu <stefan.puiu-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

 In C++11 concatenated string literals need to have a
 space in between. Found with clang++-3.4, IIRC g++-4.8 also complains about this. 

Sample error message:
dpdk/include/rte_pci.h:96:26: error: invalid suffix on literal; C++11 requires a space between literal and identifier [-Wreserved-user-defined-literal]
