netfilter: nft_set_rbtree: overlap detection with element re-addition after deletion

[ Upstream commit babc3dc9524f0bcb5a0ec61f3c3639b11508fad6 ]

This patch fixes spurious EEXIST errors.

Extend d2df92e98a34 ("netfilter: nft_set_rbtree: handle element
re-addition after deletion") to deal with elements with same end flags
in the same transation.

Reset the overlap flag as described by 7c84d41416d8 ("netfilter:
nft_set_rbtree: Detect partial overlaps on insertion").

Fixes: d2df92e98a34 ("netfilter: nft_set_rbtree: handle element re-addition after deletion")
