x86/io_delay: Break instead of fallthrough in switch statement
The current code is fine since 'case CONFIG_IO_DELAY_TYPE_NONE'
does nothing, but scripts/checkpatch.pl complains about this:
warning: Possible switch case/default not preceded by break or fallthrough comment
I like break statement better than a fallthrough comment here.
It avoids the warning and clarify the code.
No behavior change is intended.
