      The 'umidi' object will be free'd on the error path by snd_usbmidi_free()
      when tearing down the rawmidi interface. So we shouldn't try to free it
      in snd_usbmidi_create() after having registered the rawmidi interface.

      Fix the RC QPs send queue overhead computation to take into account
      two additional segments in the WQE which are needed for registration
      operations.
      
      The ATOMIC and UMR segments can't coexist together, so chose maximum out
      of them.
      
      The commit 9e65dc37 ("IB/mlx5: Fix RC transport send queue overhead

      Changes from v4:
      - as suggested by Doug Ledford, optimized spinlock usage,
      i.e. ipoib_mcast_join() is called with lock held.
      Changes from v3:
      - sync with priv->lock before flag check.
      Chages from v2:
      - Move check for OPER_UP flag state to mcast_join() to
      ensure no event worker is in progress.
      - minor style fixes.
      Changes from v1:
      - No need to lock again if error detected.
