fbdev: omapfb: Remove writeback deadcode 



Value of enum parameter 'plane' is initialized in dss_init_overlays and
cannot take the value OMAP_DSS_WB. Function dispc_ovl_setup_common could
be called with this value of parameter only from dispc_wb_setup, which has
never been used and has been removed in commit 4f55bb03
("omapfb: Remove unused writeback code"). The code in the if-branch is
unreachable.

Remove unreachable branch.
