IB/ipath: Fix and recover TXE piobuf and PBC parity errors
We can sometimes trigger parity errors due to processor speculative
reads to our write-combined memory (mostly seen on Woodcrest). Add a
stats counter for these.
Factored out the sendbuffererror buffer cancellation code so it can be
used in the new handling; suppress likely subsequent error messages if
within two jiffies of the cancellation.
Also restore 2 dropped TXE lines on hwe_bitsextant noticed while
debugging.
