The pending type can be determined based on the command opcode.
This also moves the "issue pending RDMA reads" case out of the I/O queue
handling into the generic continuation code; this should not make any
difference for the current case, since the Fabrics Connect command is
the only other continuation case currently, and there cannot be any
pending RDMA reads in that case.
