Remove duplication of table_compute_checksum function

Browse Source 
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: 1befb38b86 ("x86: Move table csum into separate file")
Fixes: 2b445e4d31 ("x86: Move table csum into separate header")
