Excessive const qualifier for local array of function pointers

Description

For instance for module net/sctp/sctp.ko instead of original:

static printfn_t *table[] = ...

C-backend outputs:
printfn_t const *table[5U] = ...

CPAchecker and Clang likely treat this as undefined behavior. GCC looks to be silent.

Thanks to Philipp Wendler for reporting the case.

After #10897 was solved this issue is not so important.
