Subject: test/power: fix build with shared library
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=4e96556a21bc60a89b05bd92163a5897ae2b43a4

test/power: fix build with shared library

Using private api `guest_channel_host_connect()`
will cause shared library build failure:
        test_power_kvm_vm.c:(.text+0x2cb):
        undefined reference to `guest_channel_host_connect'

So revert the changes done.

Fixes: d550a8cc31f3 ("app/test: enhance power manager unit tests")
