[dpdk-dev] [PATCH] mem: support page locking on FreeBSD

[Thomas Monjalon]

The function rte_mem_lock_page() was added for Linux only.
The file eal_common_memory.c is a better place to make it
available in FreeBSD also.

The issue is seen when trying to compile bnxt on FreeBSD:
	bnxt_hwrm.c: undefined reference to `rte_mem_lock_page'

Fixes: 3097de6e6bfb ("mem: get physical address of any pointer")
