loop: fix backing file reference leak on validation error
loop_change_fd() and loop_configure() call loop_check_backing_file()
to validate the new backing file. If validation fails, the reference
acquired by fget() was not dropped, leaking a file reference.
Fix this by calling fput(file) before returning the error.
