scsi: 3w-sas: 3w-9xxx: Use unsigned char for cdb
Clang warns a few times:
drivers/scsi/3w-sas.c:386:11: warning: implicit conversion from 'int' to
'char' changes value from 128 to -128 [-Wconstant-conversion]
cdb[4] = TW_ALLOCATION_LENGTH; /* allocation length */
~ ^~~~~~~~~~~~~~~~~~~~
Update cdb's type to unsigned char, which matches the type of the cdb
member in struct TW_Command_Apache.
