checkpatch: fix TYPO_SPELLING check for words with apostrophe
checkpatch reports a false TYPO_SPELLING warning for some words containing an apostrophe when run with --codespell option. A false positive is "doesn't". Occurrence of the word causes checkpatch to emit the following warning: "WARNING: 'doesn'' may be misspelled - perhaps 'doesn't'?" Modify the regex pattern to be more in line with the codespell default word matching regex. This fixes the word capture and avoids the false warning. In addition, highlight the misspelled word location by adding a caret below the word.
