Tony Luck af5ef6dafe x86/mce: Fix copy/paste error in exception table entries ...

commit 26a37ab319 upstream.

Back in commit:

  92b0729c34 ("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.

Fix: s/3/2/
