[Qemu-block] [PATCH v2 0/2] block: Add qemu_dup in osdep.c and use it

[Fam Zheng]

v2: Fix patch 1 #else branch, and "r" => "ret". [Kevin]
    Add Kevin's r-b line in patch 2.

This is an independent tiny change extracted from the image locking series,
which can be processed separately.

Improved according to Kevin's suggestion in v6 image locking series.
