Lluís Vilanova 0cebabd5e8 checkpatch: Fix whitespace checks for documentation code blocks
Prevent blank lines in documentation code blocks to be signalled as
incorrect trailing whitespace.

Code blocks in documentation are 4-column aligned, and blank lines in
them should have exactly 4 columns of trailing whitespace to prevent
QEMU's wiki to render them as separate code blocks.
