kernel.spec: Fix up mixed indents

There are several instances of mixed spaces and tabs throughout the
kernel.  This makes vim yell and rpmlint complain, so....

It doesn't look like there was any consistency in the expected tab widths
used, so I just tried to line things up as it appears to have been
intended.
