Subject: [PATCH v2 13/14] perf mem: Use more generic term for 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. Replace LFB with generic name "Cache
Fill Buffer".
