IB/ipath: Workaround problem of errormask register being overwritten
On some system hardware, we are seeing moderately common cases of the chip errormask register being overwritten due to a chip bug in iba6120 that is triggered by a vendor-specific PCIe broadcast message. This patch merely checks periodically, and corrects it if needed (the overwrite can cause us to not get error and hardware error interrupts). Also, make dd->ipath_errormask the one, true canonical source for kr_errormask, and remove references to ipath_ignorederrs as it is currently unused.
