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
da0fe6e68e10 ("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 '*'.
Fixes: da0fe6e68e10 ("x86/alternative: Add indirect call patching")
