xtoptions + quota: parse and store 64bit values?

[JP Abgrall <jpa@google.com>]

Without this change, my kernel's xt_quota.c::quota_mt_check() doesn't
see the values.

Subject: [PATCH] xtoptions + quota: parse and store 64bit values

The xtables_strtoul() would cram a long long into a long.
The parse_int would try to cram a UINT64 into a long.
The quota_parse would just ignore whatever value was parsed.
