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.

Now that we have xfer to track data direction, the length field can be

This field is used to decide whether data needs to be transferred back
to the host after a command is completed.
Previously, this was determined using the length field, and length was
cleared to 0 after a transfer was completed. However, length will be
used in future patches after a host to controller transfer completes, so
we need some other way to tell what kind of data transfer is required.

vtophys() was checking for out-of-range addresses incorrectly: vfn_2mb
is already shifted to account for 2 MB hugepages, but it was being
compared with a mask that did not account for the shift. This would
allow out-of-bounds access to the 128tb map array for certain invalid
addresses (it had no effect on addresses within the valid userspace
range).

Since we used u64 to mask CPU cores, the available number of CPU
is 64, for default RTE_MAX_LCORE in DPDK, the value is 128, in some
cases(e.g.: when nr_io_queues > 4) we can get the wrong lcore ID.
