When destroying a connection, we need to check if we got to
full feature phase before freeing any io channels. This is because
the io channels are only allocated as part of a successful login.
The Calsoft iSCSI test suite has tests which will fail login.
Since the test system was just using a malloc backend with memcpy,
so even though a channel was NULL in some cases, it was never used
since the memcpy engine doesn't need it.
This prepares for some future patches which extend the use
of io channels in the bdev layer.

The ISID field is a 6-byte field in network (big-endian) byte order.
The previous code was casting the uint8_t isid[6] value into uint64_t,
which was actually casting the address of the first byte of isid (not
the contents of the array), and it was also not correctly converting
byte order.

The VirtualBox emulated NVMe device will intermittently
hang on the first read/write command after an I/O
qpair has been allocated. The frequency of the hang
diminishes if a delay is added after allocating the I/O
qpair - until it disappears completely with a 100us delay.
So add a quirk to insert this delay.
Note - the 100us delay was tested by running
the hello_world example app 50000 times.

Vhost needs to register memory given by guest in VFIO container to be
able to do any DMA using this memory.
Currently DPDK doesn't provide any interface to handle guest memory, so
for now lets find container fd in /proc/self/fd/ directory and provide
some VFIO internal API that finally should extend DPDK API.
