Consistently use array_size() to calculate the size of ip_vs_conn_tab
in bytes.

Flagged by Coccinelle:
 WARNING: array_size is already used (line 1498) to compute the same size

No functional change intended.
Compile tested only.

v3
- Correct division by 1024. It was applied to the wrong variable in v2.
- Add Horatiu's Reviewed-by tag
v2
- Retain division by 1024, which was lost in v1
