perf arm_spe: Fix memset subclass in operation

Browse source

The operation subclass is extracted from bits [7..1] of the payload.
Since bit [0] is not parsed, there is no chance to match the memset type
(0x25). As a result, the memset payload is never parsed successfully.

Instead of extracting a unified bit field, change to extract the
specific bits for each operation subclass.
