ipoib: Fix incorrectly computed IPOIB_CM_RX_SG value.

The computed IPOIB_CM_RX_SG is too small. It doesn't account for fallback
to mbuf clusters when jumbo frames are not available and it also doesn't
account for the packet header and trailer mbuf.

This causes a memory overwrite situation when IPOIB_CM is configured.

While at it add a kernel assert to ensure the mapping array is not overwritten.

output queue blocking the transmit path.

sys: general adoption of SPDX licensing ID tags.

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using misidentified many licenses so this was mostly a manual - error
prone - task.

The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.

No functional change intended.
