fbdev: udlfb: Remove redundant initialization to variable identical 

The variable identical is being initialized with a value that is never
read. The variable is being re-assigned later on. The initialization is
redundant and can be removed.

Cleans up clang scan-build warning:
drivers/video/fbdev/udlfb.c:373:6: warning: Value stored to 'identical'
during its initialization is never read [deadcode.DeadStores]
