Daniel Vetter 2cbae7e637 drm: Extract drm_master_open 
And pull out the primary_client check to make it really obvious that
this can't happen on control/render nodes. Bonus that we can avoid the
master lock in this case.

v2: Don't leak locks on error path (and simplify control flow while
at it), reported by Julia.
