Dave Taht c48994baef sch_cake: constify inverse square root cache 
sch_cake uses a cache of the first 16 values of the inverse square root
calculation for the Cobalt AQM to save some cycles on the fast path.
This cache is populated when the qdisc is first loaded, but there's
really no reason why it can't just be pre-populated. So change it to be
pre-populated with constants, which also makes it possible to constify
it.

This gives a modest space saving for the module (not counting debug data):
.text:  -224 bytes
.rodata: +80 bytes
.bss:    -64 bytes
Total:  -192 bytes
