git: sbin/newfs_hammer: Cleanup blocks with a single statement

[Thomas Nikolajsen]

No need to refer to linux, we have style.9, see below.

Regarding braces: as I read style.9 the focus is on code redability,
not only what can be inferred from syntax.

If you would like to change style.9, please do that.

    sbin/newfs_hammer: Cleanup blocks with a single statement
    
    This commit basically does the same as what Linux kernel's coding
    style mentions for braces, which is basically the same with BSDs.

     Braces that
     are not necessary may be left out, but always use braces around complex
     or confusing sequences, for example if any part of a conditional is
     multi-line, use braces for all parts of the conditional, and use braces
     around multi-line substatements of loops or conditionals even if they are
     theoretically one statement from the compiler's point of view.
