[IB] mthca: first pass at catastrophic error reporting
Add some initial support for detecting and reporting catastrophic
errors reported by Mellanox HCAs. We start a periodic timer which
polls the catastrophic error reporting buffer in device memory. If an
error is detected, we dump the contents of the buffer for port-mortem
debugging, and report a fatal asynchronous error to higher levels.
In the future we can try to recover from these errors by resetting the
device, but this will require some work in higher-level code as well.
Let's get this in now, so that we at least get catastrophic errors
reported in logs.
