Subject: eal/windows: cleanup virt2phys handle
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=23ce9e0a193636e2f5ec9b386ddd5307c17e9723;p=dpdk.git

eal/windows: cleanup virt2phys handle

eal_mem_virt2phys_init() opens a handle for use by rte_mem_virt2phy().
Close this handle on EAL cleanup.

Fixes: 2a5d547a4a9b ("eal/windows: implement basic memory management")
