[PATCH] IB/ipath: memory management cleanups

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).
