dpif-netdev: fix dp_netdev_free()
dp_netdev_free() must free 'dp->upcall_rwlock', but when upcalls are
disabled (if the datapath is being freed upcalls should be disabled)
'dp->upcall_rwlock' is taken and freeing it causes an assertion to
fail.
This commit takes makes sure that the upcalls are disabled and
releases 'dp->upcall_rwlock' before freeing it. A simple testcase is
added to detect the failure.
