Dapeng Mi e7fcc54524 perf/x86/intel: Fix OMR snoop information parsing issues 
When omr_source is 0x2, the omr_snoop (bit[6]) and omr_promoted (bit[7])
fields are combined to represent the snoop information. However, the
omr_promoted field was not left-shifted by 1 bit, resulting in incorrect
snoop information.

Besides, the snoop information parsing is not accurate for some OMR
sources, like the snoop information should be SNOOP_NONE for these memory
access (omr_source >= 7) instead of SNOOP_HIT.

Fix these issues.
