After commit 905e224849fbbed1719e0add231b00e2d570b3b4 (image_qa: fix
error handling), any unexpected exceptions in do_image_qa() would result
in a variable being set, but never used, effectively hiding the error.
Since image_qa now calls oe.qa.exit_if_errors(), remove the support for
oe.utils.ImageQAFailed and instead rely on the called functions to call
oe.qa.handle_error() themselves. This matches what do_package_qa() does.
Also update the description of do_image_qa() to explain that the called
functions are expected to call oe.qa.handle_error() themselves.
