Subject: net sched actions: avoid bitwise operation on signed value in pedit
Patch-mainline: v4.19-rc1
Git-commit: 430527415398cf7e741f5e2f11324a8df9093327
References: bsc#1109837

Since char can be unsigned or signed, and bitwise operators may have
implementation-dependent results when performed on signed operands,
declare 'u8 *' operand instead.
