net: ipa: avoid a null pointer dereference
Dan Carpenter reported that Smatch found an instance where a pointer which had previously been assumed could be null (as indicated by a null check) was later dereferenced without a similar check. In practice this doesn't lead to a problem because currently the pointers used are all non-null. Nevertheless this patch addresses the reported problem. In addition, I spotted another bug that arose in the same commit. When the command to initialize a routing table memory region was added, the number of entries computed for the non-hashed table was wrong (it ended up being a Boolean rather than the count intended). This bug is fixed here as well.
