[PATCH 1/1]drm/gma500: mdfld: Remove unncessary code

[Maninder Singh]

sender is dereferrenced before NULL check
struct drm_device *dev = sender->dev;

and due to this we get warning during static analysis:
warn: variable dereferenced before check 'sender'

__read_panel_data Function is called by mdfld_dsi_read_mcs
and there is a same check, Thus removing the check from
__read_panel_data.
