avr32: don't mask signals in the error path
The current handle_signal() implementation is broken - it will mask signals if we fail to setup the signal stack frame, which isn't the desired behaviour, we should only be masking signals if we succeed in setting up the stack frame. It looks like this code was copied from the old (broken) arm implementation but wasn't updated when the arm code was fixed in commit a6c61e9d ("[ARM] 3168/1: Update ARM signal delivery and masking").
