Boris Gjenero 4077eac839 Fix return address when data_abort_handler skips faulting instruction. 
When writing a value to PC, execution continues at that location,
so subtracting 4 returns to the next instruction. Previously, two
instructions after the faulting instruction were being skipped, causing
safe_read functions to return true even if a data abort happened.
