r8152: Fix potential PM refcount imbalance

[ Upstream commit 9c23aa51477a37f8b56c3c40192248db0663c196 ]

rtl8152_close() takes the refcount via usb_autopm_get_interface() but
it doesn't release when RTL8152_UNPLUG test hits.  This may lead to
the imbalance of PM refcount.  This patch addresses it.
