[kvm-unit-tests PATCH v1 08/10] s390x: gs: turn off formatter for inline assembly

[Nico Boehr <nrb@linux.ibm.com>]

clang-format does not properly understand the code and aligns the first
opening quote on consecutive lines with the last opening quote on the
previous line like so:

" some string " CONCATED_WITH_MACRO " continues here "
                                    " weird indent for some reason"

Disable clang-format for this block of code and properly align the
indented asm with the opening parenthesis.
