cxgbe nic TLS: Fix requests with 8 bytes of immediate data padding

Requests whose immediate data do not end on a 16-byte boundary are
padded with zeroes before the next WR command. Since ULP commands are
8 byte aligned, if there are more than 8 bytes of padding, the
immediate data is padded with zeroes up to an 8 byte boundary and the
last 8 bytes contain a ULP NOOP command.

In the case of exactly 8 bytes of padding, the result should be that
no zeroes are inserted, only the ULP NOOP. However, the code was
actually inserting 8 bytes of zero padding followed by the ULP NOOP
causing the following real command to be misaligned. Fix this by
skipping the zero padding if there exactly 8 padding bytes.

tcp: remove INP_TIMEWAIT flag

Mechanically cleanup INP_TIMEWAIT from the kernel sources. After
0d7445193ab, this commit shall not cause any functional changes.

Note: this flag was very often checked together with INP_DROPPED.
If we modify in_pcblookup*() not to return INP_DROPPED pcbs, we
will be able to remove most of this checks and turn them to
assertions. Some of them can be turned into assertions right now,
but that should be carefully done on a case by case basis.
