[PATCH 3/5] hw/core: Pass errp to load_image_targphys_as()

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

Pass errp to load_image_targphys_as() in generic-loader and
guest-loader to capture detailed error information from the
loader functions.

Use error_prepend() instead of error_setg() to preserve the
underlying error details while adding context about which image
failed to load.
