Made in-memory rcvhdrq tail update be in dma_alloc'ed memory, not random user or special kernel (needed for ppc, also "just the right thing to do"). Some cleanups to make unexpected link transitions less likely to produce complaints about packet errors, and also to not leave SMA packets stuck and unable to go out. A few other random debug and comment cleanups. Always init rcvhdrq head/tail registers to 0, to avoid race conditions (should have been that way some time ago).
