x86/mm/pkeys: Do not skip PKRU register if debug registers are not used

__show_regs() fails to dump the PKRU state when the debug registers are in
their default state because there is a return statement on the debug
register state.

Change the logic to report PKRU value even when debug registers are in
their default state.
