x86/alternatives: Add pr_fmt() to debug macros
... in order to have debug output prefixed with the pr_fmt text "SMP
alternatives:" which allows easy grepping:
$ dmesg | grep "SMP alternatives"
[ 0.167783] SMP alternatives: alt table ffffffff8272c780, -> ffffffff8272fd6e
[ 0.168620] SMP alternatives: feat: 3*32+16, old: (x86_64_start_kernel+0x37/0x73 \
(ffffffff826093f7) len: 5), repl: (ffffffff8272fd6e, len: 5), pad: 0
[ 0.170103] SMP alternatives: ffffffff826093f7: old_insn: e8 54 a8 da fe
[ 0.171184] SMP alternatives: ffffffff8272fd6e: rpl_insn: e8 cd 3e c8 fe
