x86/pkeys/selftests: Remove dead debugging code, fix dprint_in_signal There is some noisy debug code at the end of the signal handler. It was disabled by an early, unconditional "return". However, that return also hid a dprint_in_signal=0, which kept dprint_in_signal=1 and effectively locked us into permanent dprint_in_signal=1 behavior. Remove the return and the dead code, fixing dprint_in_signal.
