On Quark SE x86 core, the usage of the inline funtion: net_nbuf_family
is optimized by the compiler in a way that the ARP verification
of the protocol family fails. This leads the native stack to never
respond to ARP requests.
This commit fixes the issue by recoding the verification flow to get
the family value before the evaluation.

Previously the code was using the size of the user data part
to determine whether the buf was a data fragment or RX/TX
buf. This is not enough as we might have a buffer that has
user data but is still allocated from data pool.
This commit changes the detection logic. Now the pool free
pointer is checked against the data pool fifo pointer. If
those match then the buf was allocated from data pool.

LQI is provided the same way as Linux does, so it can push it everytime

This avoids bloating the radio API by adding a function to get current
LQI and it optimizes the usage of the fragment as its minimal size is
128. Knowing that 802.15.4 frame cannot be bigger than 127 bytes, it
thus finds a usage for the tail byte.
