[PATCH] Staging: xgifb: vb_util: Fixed sparse warning of bit truncation due to cast

[Shivani Bhardwaj]

Fixed the warning generated by sparse that 'cast truncates bits from
constant value' by typecasting unsigned values to u8 as their logical
operation is being performed with and stored in a u8 type variable.
