Subject: hw/arm/smmuv3: Report F_STE_FETCH fault address in correct word
 position

Git-commit: b255cafb59578d16716186ed955717bc8f87bdb7

The smmuv3_record_event() function that generates the F_STE_FETCH error
uses the EVT_SET_ADDR macro to record the fetch address, placing it in
32-bit words 4 and 5.

The correct position for this address is in words 6 and 7, per the
SMMUv3 Architecture Specification.

Update the function to use the EVT_SET_ADDR2 macro instead, which is the
macro intended for writing to these words.

ref. ARM IHI 0070C, section 7.3.4.
