[PATCH] vmcoreinfo: add kallsyms_num_syms symbol

[Stephen Brennan]

The rest of the kallsyms symbols are useless without knowing the number
of symbols in the table. In an earlier patch, I somehow dropped the
kallsyms_num_syms symbol, so add it back in.

Fixes: 5fd8fea935a1 ("vmcoreinfo: include kallsyms symbols")

Hi Baoquan & Andrew,

I made a silly omission in the above mentioned commit, which just got merged
via Andrew's non-mm pull request yesterday. I must have dropped it as I
cherry-picked between versions. Would you be able to queue this up with whatever
fixes you'll send for the 6.0 rc's?

Thanks, and sorry!
Stephen
