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'.
