checkpatch: avoid "spaces required around that ':'" false positive
Since commit 1f65f947a6a8 ("checkpatch: add checks for question mark and colon spacing") back in 2008, checkpatch has reported false positive for asm volatile uses of "::" checkpatch thinks colons should always have spaces around it. Add an exception for colons with colons on either side for this valid asm volatile (and c++) use.
