Leo Yan 51ba539f5b perf arm-spe: Don't set data source if it's not a memory operation 
Except for memory load and store operations, ARM SPE records also can
support other operation types, bug when set the data source field the
current code assumes a record is a either load operation or store
operation, this leads to wrongly synthesize memory samples.

This patch strictly checks the record operation type, it only sets data
source only for the operation types ARM_SPE_LD and ARM_SPE_ST,
otherwise, returns zero for data source.  Therefore, we can synthesize
memory samples only when data source is a non-zero value, the function
arm_spe__is_memory_event() is useless and removed.

Fixes: e55ed3423c ("perf arm-spe: Synthesize memory event")
