Michael J. Ruhl fe4e74eeb2 IB/hfi1: Initialize TID lists to avoid crash on cleanup
The expected receive lists (tid_xxx_list) are not initialized until
late in the receive context initialization.  If an error happens
before the initialization, a NULL pointer access will occur during
cleanup.

Initialized the lists sooner rather than later to avoid this Oops:
