[PATCH] video: fbdev: udlfb: Remove redundant initialization of

Integer variable 'identical' is being initialized however
this value is never read as 'identical' is assigned the result
of 'start + (width - end)'. Remove the redundant assignment.
At the same time, adjust the declarations order of variables
to keep the "upside-down x-mas tree" look of them.

Clean up clang warning:

drivers/video/fbdev/udlfb.c:370:6: warning: Value stored to 'identical'
during its initialization is never read
[clang-analyzer-deadcode.DeadStores]
