block/raw-posix: Linux compat-ioctl warning workaround

On Linux x86_64 host with 32bit userspace, running

Strip trailing '\n' from error_report()'s first argument

error_report() prepends location, and appends a newline. The message

vdi: Avoid direct AIO callback

bdrv_aio_* must not call the callback before returning to its caller. In vdi,
this could happen in some error cases. This starts the real requests processing
in a BH to avoid this situation.

qemu-img create: Fix displayed default cluster size

When not specifying a cluster size on the command line, qemu-img printed
a cluster size of 0:
