The spec requires that NQNs are null terminated and maximum of 223 bytes
long, despite the Connect command fields being larger (256 bytes), so
add checks for both subsystem NQN and host NQN before using them as null
terminated strings.

Since we bind the NVMe device to UIO driver to protect against native
NVMe driver, but for Admin queue, there are still INTx interrupts
exist, as all the completion for Admin queue will be processed in
user space, so we don't need INTx anymore.

Make sure any partition tables or other random data on the disks is
cleaned up before running the tests, rather than trying to clean it up
on failure when the system is in a potentially bad state.

This is causing issues during shutdown because the poller removal is not

The lcore_id field in the get_iscsi_connections RPC was removed in
commit 5d8c94536a7d1d4c1f0ee3349188bf0e7e8c9e74; add a field to
spdk_iscsi_conn to track the lcore so this can be re-added.

This should enhance performance, since the hardware admin queue poll
function takes a mutex and should not be in the performance path.

This leaves more flexibility for future changes to the poller
representation without requiring API changes (after this one).
It also prevents the user from accidentally using poller fields in a
non-thread-safe way, since they can't be accessed directly anymore.
