drm/msm/dsi: Fix missing put_device() call in dsi_get_phy

Browse Source 
commit c04c3148ca upstream.

If of_find_device_by_node() succeeds, dsi_get_phy() doesn't
a corresponding put_device(). Thus add put_device() to fix the exception
handling.

Fixes: ec31abf ("drm/msm/dsi: Separate PHY to another platform device")
