Subject: [PATCH v4 7/8] perf mem: Print "LFB/MAB" for PERF_MEM_LVLNUM_LFB

A hw component to track outstanding L1 Data Cache misses is called
LFB (Line Fill Buffer) on Intel and Arm. However similar component
exists on other arch with different names, for ex, it's called MAB
(Miss Address Buffer) on AMD. Use 'LFB/MAB' instead of just 'LFB'.
