fault_inject: Don't rely on "return value" from WRITE_ONCE()
It's a bit weird that WRITE_ONCE() evaluates to the value it stores and it's different to smp_store_release(), which can't be used this way. In preparation for preventing this in WRITE_ONCE(), change the fault injection code to use a local variable instead.
