net/tcp_sigpool: Fix some off by one bugs

The "cpool_populated" variable is the number of elements in the cpool[]
array that have been populated.  It is incremented in
tcp_sigpool_alloc_ahash() every time we populate a new element.
Unpopulated elements are NULL but if we have populated every element then
this code will read one element beyond the end of the array.
