net: frag helper functions for mem limit tracking
This change is primarily a preparation to ease the extension of memory limit tracking. The change does reduce the number atomic operation, during freeing of a frag queue. This does introduce a some performance improvement, as these atomic operations are at the core of the performance problems seen on NUMA systems.
