IB/qib: Clean up properly if qib_init() fails

If qib_init() fails, the driver fails to free memory, unregister
device files, and unregister with the PCIe framework. The driver will
unload without error but a subsequent driver load will cause the
system to panic.  This was found by changing the 7220 code to load the
serdes microcode separately and not installing the microcode file.
