The bsdapp part was missing in commit 57c24af85d9eaa81549a212169605b4e2468a29f.
This commit adds a dummy rte_mem_virt2phy() to fix the compilation of
DPDK under BSD. This function is only used when the debug option
"--no-huge" is given, to get the physical address of mempools in memory.
As a result, it seems acceptable for now to implement a dummy function
to fix the compilation as the usual case (using contigmem module) works
properly.
