target-i386: Use switch in check_hw_breakpoints()
Replace an if statement using magic numbers for breakpoint type with a
more explicit switch statement. This is to aid readability.
Change the return type and force_dr6_update argument type to bool.
While at it, fix Coding Style issues (missing braces).
