[Qemu-trivial] [PATCH] qemu-img: fix error messages emitted by img_open()

[Reda Sallahi <fullmanet@gmail.com>]

img_open_file() and img_open_opts() were printing error messages with a
duplicate part because of a wrong use of error_reportf_err() (e.g.
qemu-img: Could not open 'foo': Could not open 'foo': No such file or directory)

This change uses error_report_err() instead to eliminate the duplicate part.
