commit c72afedce794a7251fd9c822e3bfc89f870b9fc1

    target: cortex_a: fix regs invalidation when -defer-examine
    
    The code for cortex_a allocates the register cache during the very
    first examine of the target.
    To prevent a segmentation fault in assert_reset(), the call to
    register_cache_invalidate() is guarded by target_was_examined().
    
    But for targets with -defer-examine, the target is set as not
    examined in handle_target_reset() just before entering in
    assert_reset().
    
    This causes registers to not be invalidated while reset a target
    examined but with -defer-examine.
    
    Change the condition and invalidate the register cache if it has
    been already allocated.
