x86/mce: Fix copy/paste error in exception table entries
Back in commit: 92b0729c34cab ("x86/mm, x86/mce: Add memcpy_mcsafe()") ... I made a copy/paste error setting up the exception table entries and ended up with two for label .L_cache_w3 and none for .L_cache_w2. This means that if we take a machine check on: .L_cache_w2: movq 2*8(%rsi), %r10 then we don't have an exception table entry for this instruction and we can't recover.
