gfile: don't report completion twice on g_file_load_contents error

When an error occurs while reading the file input stream in
g_file_load_contents (e.g. because the operation was cancelled), the
code is correctly calling g_task_return_error(), but in the callback
from the close operation, g_task_return_boolean() will be called again.

Code that cleans up its state in the async callback will then be called
twice, leading to invalid memory access.
