checkpatch: remove false warning for commit reference
Checkpatch warns of an incorrect commit reference style for any
hexadecimal number of 12 digits and more.
Numbers of 12 digits are not necessarily commit ids.
For an example provoking the problem see
https://patchwork.kernel.org/patch/9170897/
Checkpatch should only warn if the number refers to an existing commit.
