[patch] sparc: indent an if statement

[Dan Carpenter]

The code works fine, but my static checker complains when we don't
indent our if statements.

This is one ugly looking function....
If we are anyway fixing indent thus increasign readability,
then how about doing just a little more.
Like this untested patch.

I do not claim it is readable, but it is an improvement.
