[Patch v10 1/6] core/loader: Use qemu_open() instead of open() in get_image_size()

[Vishal Chourasia <vishalc@linux.ibm.com>]

Replace open() with qemu_open() which provides better error handling
via the Error object, automatically sets O_CLOEXEC, and supports FD
passing with /dev/fdset.

Currently pass errp argument as NULL.
