drm: fix mutex leak in drm_dp_get_mst_branch_device
commit 30730c7f5943b3beace1e29f7f1476e05de3da14 upstream.
In Linux 4.3-rc5, there is an error case in drm_dp_get_branch_device
that returns without releasing mgr->lock, resulting a spew of kernel
messages about a kernel work function possibly having leaked a mutex
and presumably more serious adverse consequences later. This patch
changes the error to "goto out" to unlock the mutex before returning.
