Reset the device when an internal error is detected.
Also, detect errors by polling the error buffer rather than using
interrupts. This is more robust and doesn't depend on MSI-X. Remove
the old interrupt handler entirely, since we don't want to support two
mechanisms for detecting internal errors.

When warning about out-of-date firmware, current mthca code messes up
the formatting of the version if the subminor doesn't have three
digits. It doesn't fill the field with 0s so we end up with:
ib_mthca 0000:0b:00.0: HCA FW version 1.1. 0 is old (1.2. 0 is current).
Change the format from "%3d" to "%03d" to get the right thing printed.

The mthca driver supports both MSI and MSI-X. However, MSI-X works with
all hardware that the driver handles, and provides a superset of what
MSI does, so there's no point in having code for both. Schedule MSI
support for removal in 2008 to give anyone who actually needs MSI and
who can't use MSI time to speak up.

I'm sure we'll have it fixed properly soon enough, but for now we should

1) Remove CONFIG_PCI ifdefs. PCI is required in Kconfig.
2) Break up setup_netjet_s() into three separate internal functions.
This helps facilitate upcoming use of PCI hotplug API, and in addition
makes the code much easier to follow.

Initializing 'f0' is not strictly necessary in either case, AFAICS.

complex flow of control in each function, I feel it is wiser and
