perf vendor events arm64: Fix incorrect Hisi hip08 L3 metrics

Commit dd705060a09c0bcf ("perf vendor events arm64: Add Hisi hip08 L3
metrics") add L3 metrics of hip08, but some metrics (IF_BP_MISP_BR_RET,
IF_BP_MISP_BR_RET, IF_BP_MISP_BR_BL) have incorrect event number due to
the mistakes in document, which caused incorrect result. Fix the
incorrect metrics.

Before:

  65,811,214,308 armv8_pmuv3_0/event=0x1014/ # 18.87 push_branch
   # -40.19 other_branch
  3,564,316,780 BR_MIS_PRED # 0.51 indirect_branch
   # 21.81 pop_branch

After:

  6,537,146,245 BR_MIS_PRED # 0.48 indirect_branch
   # 0.47 pop_branch
   # 0.00 push_branch
   # 0.05 other_branch
