Robert Lubos ea191bddaf net: pkt: Fix fixed buffer allocation with headroom bug 
The size calculation for the first buffer, in case extra headroom is
requested, had a bug which could result in a size variable underflow
followed by net_buf exhaustion.

In case the net_buf size was larger than requested size, but smaller
than requested size + headroom, the whole buffer size was subtracted
from the requested size. This however did not take the extra headroom
into account and in effect could result in underflow.
