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.

The system must be powercycled to clear a HT CRC error; reloading the
driver is not enough.

Prior to this change, the driver was not able to support a HT and PCIE
card simultaneously present in the same machine.

0x08 is the HT capability, while PCI_CAP_ID_HT_IRQCONF would be
the subtype 0x80 that mpic_scan_ht_pic() uses.
Rename PCI_CAP_ID_HT_IRQCONF into PCI_CAP_ID_HT.
And by the way, use it in the ipath driver instead of defining its
own HT_CAPABILITY_ID.

Also added the word "Hardware" after "Fatal" to make it more obvious
that it's hardware, not software.
