Remove duplication of table_compute_checksum function
It seems like there was some merge error when first cleaning up and
sharing this function. We have both an inline version of the function
in include/tables_csum.h and a non-inline version in lib/tables_csum.c.
Rework things so that we only have the non-inline version (due to number
of calls, we should not inline this).
Fixes: 1befb38b8682 ("x86: Move table csum into separate file")
Fixes: 2b445e4d3194 ("x86: Move table csum into separate header")
