x86/alternative: Correct feature bit debug output

In

  https://lore.kernel.org/r/20231206110636.GBZXBVvCWj2IDjVk4c@fat_crate.local

I wanted to adjust the alternative patching debug output to the new
changes introduced by

  da0fe6e ("x86/alternative: Add indirect call patching")

but removed the '*' which denotes the ->x86_capability word. The correct
output should be, for example:

  [    0.230071] SMP alternatives: feat: 11*32+15, old: (entry_SYSCALL_64_after_hwframe+0x5a/0x77 (ffffffff81c000c2) len: 16), repl: (ffffffff89ae896a, len: 5) flags: 0x0

while the incorrect one says "... 1132+15" currently.

Add back the '*'.
