[PATCH] Doc: Correct the name of qemu-img dd parameter

[Rajat Dhasmana]

In the qemu-img documentation, one of the option for the dd command
is mentioned as size whereas it is the skip parameter[1] that is also
available in the dd command.

skip=BLOCKS
    skip BLOCKS ibs-sized blocks at start of input

This patch corrects the documentation.
