Fix autoconf detection of super_setup_bdi_name
The previous autoconf test for the presence of super_setup_bdi_name()
uses an invocation with an incorrect type signature, producing a
warning by the compiler when the test is run. This gets elevated to an
error when compiling with -Werror=format-security, causing autoconf to
falsely infer super_setup_bdi_name() is not present. This updates the
testing code to match the invocation used in
include/linux/vfs_compat.h.
