Fix unused variable warnings in hwpmc_mod.c

With clang 15, the following -Werror warnings are produced:

    sys/dev/hwpmc/hwpmc_mod.c:4805:6: error: variable 'nfree' set but not used [-Werror,-Wunused-but-set-variable]
            int nfree;
                ^
    sys/dev/hwpmc/hwpmc_mod.c:4804:6: error: variable 'ncallchains' set but not used [-Werror,-Wunused-but-set-variable]
            int ncallchains;
                ^

The 'nfree' and 'ncallchains' variables were used in KASSERTs, but these
were removed due to refactoring in d9f1b8dbf29d. Remove the variables
since they no longer serve any purpose.
