When the v3 hardware sees more than one finger, it uses the semi-mt
protocol to report the touches. However, it currently works when
num_fingers is 0, 1 or 2, but when it is 3 and above, it sends only 1
finger as if num_fingers was 1.
This confuses userspace which knows how to deal with extra fingers
when all the slots are used, but not when some are missing.

Offsets and total length returned by the ip_set_elem_len()
calculated incorrectly as initial set element length (i.e.
len parameter) is used multiple times in offset calculations,
also affecting set element total length.
Use initial set element length as start offset, do not add aligned
extension offset to the offset. Return offset as total length of
the set element.
This reduces memory requirements on per element basic for the
hash:* type of sets.
