fix(TFTF): ensure robustness of SError inject test

A previous patch [1] fixed a race condition by moving a store
instruction earlier in the SError inject test. However, this
was not made robust by introducing the correct data barrier
instructions. This patch introduces dsb instructions to ensure
the race condition does not return.
