libxtables: xtoptions: Fix for garbage access in xtables_options_xfrm()

Allocation of the temporary array did not account for a terminating NULL
entry, causing array boundary overstepping in the called
xtables_merge_options(), causing spurious errors in extension parameter
parsing.

Fixes: ed8c3ea4015f0 ("libxtables: Combine the two extension option mergers")
