[PATCH] block.h: remove outdated comment

[Emanuele Giuseppe Esposito]

The comment "disk I/O throttling" doesn't make any sense at all
any more. It was added in commit 0563e191516 to describe
bdrv_io_limits_enable()/disable(), which were removed in commit
97148076, so the comment is just a forgotten leftover.
