qemu: blockPeek: Fix filling of the return buffer

Commit 3956af495e broke the blockPeek API since virStorageFileRead
allocates a return buffer and fills it with the data, while the API
fills a user-provided buffer. This did not get caught by the compiler
since the API prototype uses a 'void *'.

Fix it by transferring the data from the allocated buffer to the user
provided buffer.
