[PATCH] checkpatch: Don't complain about long "Fixes:" lines

[Michael Ellerman <mpe@ellerman.id.au>]

We encourage people to mention the commit they are fixing, if any, using
a Fixes line, see SubmittingPatches.

Although it's not mentioned explicitly, it's preferable if the Fixes
line is not wrapped, so skip Fixes lines when checking for overlength
lines.
