Previously the bitseq alloc was allocating the first available bit from the begining of the sequence. With this commit the bitseq alloc will proceed from the current allocation. This change will affect the way ipam and vni allocation is done currently. The ip allocation will be done sequentially from the previous allocation as opposed to the first available IP.

The byteoffset calculation was skewed to double include the offset value calculated. The double calculation happens if the starting ordinal is part of the head sequence block. This error in calculation could result in duplicate but getting allocated eventually propogating to ipam and vni id allocations Signed-off-by: Abhinandan Prativadi <abhi@docker.com> (cherry picked from commit 6ed2ad9)
